There are several types of capacitors including non-polarized, polarized, variable, and trimmer capacitors. Non-polarized capacitors can be connected either way in a circuit and include ceramic, mica, and some electrolytic capacitors. Polarized capacitors maintain a positive and negative terminal and are often used in timing circuits or to filter signals. Variable capacitors have movable plates that allow the capacitance to be varied, making them useful in radio tuners. Trimmer capacitors are small variable capacitors adjusted with a screwdriver during circuit assembly.

Capacitor Presentation
A capacitor is a device that stores electric charge between two conductive plates separated by an insulator. When a voltage is applied across the plates, charges of opposite polarity accumulate on each plate. The amount of charge stored depends on the capacitor's capacitance, which is determined by the size, number, and distance between plates as well as the dielectric material between the plates. Capacitors are used in electrical circuits for functions like energy storage, voltage regulation, timing, and filtering. They can be connected in parallel to increase total capacitance or in series to decrease it. Common applications include power supplies, audio equipment, and sensors.

They can be connected in series or parallel configurations, which affects how voltage and charge are distributed across the capacitors.
Semiconductors
1) Semiconductors have two energy bands called the valence band and conduction band, separated by a forbidden gap.
2) They can be classified as intrinsic or extrinsic. Intrinsic semiconductors are pure, while extrinsic are doped with impurities to alter conductivity.
3) Doping a semiconductor by adding impurities that add free electrons makes it an n-type semiconductor, while adding impurities that add free holes makes it a p-type semiconductor. A p-n junction formed from a p-type and n-type semiconductor can function as a rectifier.

Capacitors.ppt
Capacitors are energy storage devices composed of two conductive plates separated by an insulator. The key equations for capacitance in parallel and series are presented. In parallel, the total capacitance is the sum of the individual capacitances. In series, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitances. Charging and discharging behaviors are also summarized.
Mechanism of-a-capacitor
Our group members for this project are A. F. M. Foysal Islam, Pias Ahmmed, Md. Abed Ceum, Md. Farhan Islam, and Pronay Kumar Tarafdaer. A capacitor is a passive two-terminal electrical component that stores energy in its electric field by accumulating positive charge on one plate and negative charge on the other when connected to a battery. Increasing the surface area of the plates, decreasing the spacing between plates, and increasing the dielectric constant of the material between the plates improves a capacitor's ability to store charge. There are fixed, electrolytic, and variable types of capacitors that use different materials and configurations.
Physics capacitors w11-l23
A capacitor is a device that stores electrical charge and energy. It consists of two conducting plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, electric charges of equal magnitude but opposite polarity build up on each plate. This creates an electric field within the capacitor. The amount of charge stored for a given voltage is proportional to the capacitance, measured in Farads, which depends on the size, shape and separation of the plates as well as the dielectric material. Capacitors are used widely in electronic circuits to store charge and energy, such as in camera flashes. The basic formula relating capacitance C, charge Q, and voltage V is Q = CV.

Capacitors
Capacitors are electronic components that store electric charge between two conductive plates separated by an insulating material called a dielectric. The capacitance of a capacitor depends on the surface area and distance between the plates, as well as the dielectric material. Common types of capacitors include electrolytic, ceramic, mica, paper, and film capacitors. Multilayer ceramic capacitors (MLCCs) contain many thin layers that increase their capacitance while maintaining a small size, making them well-suited for applications requiring small capacitances. Capacitors are used widely in electronic devices to filter signals and store energy.
Module No. 30
1. The document discusses capacitors, eddy currents, Lenz's law, and Faraday's laws of electromagnetic induction. It provides details on how capacitors work, different types of capacitors, and their uses.
2. It explains that when a conductor moves through a magnetic field, an eddy current is induced in the conductor due to electromagnetic induction. Lenz's law states that the direction of this induced current will oppose the change that created it.
3. Faraday's laws of electromagnetic induction establish that a voltage is induced in a circuit when there is a change in the magnetic flux through the circuit. The magnitude of this induced voltage is proportional to the rate of change of flux.
Capacitors
Capacitors store energy and have frequency-dependent behavior. They are made up of two conducting plates separated by an insulator. The voltage across a capacitor is proportional to the charge stored on its plates according to the equation Q = CV, where Q is the charge, C is the capacitance, and V is the voltage. The relationship between current and voltage in a capacitor is ic(t) = C dvc(t)/dt, meaning that current is proportional to the rate of change of voltage. If the voltage across a capacitor is decreasing, the current will be negative.
Chapter 37
The document provides an overview of capacitance, magnetism, and electromagnetism for an ASE certification exam. It defines key concepts such as capacitance, dielectric materials, magnetic flux lines, electromagnets, and how electricity and magnetism are related. Objectives include explaining factors that influence capacitance and how capacitors are used in various applications such as filters, memory storage, and microphones.
Capacitor
This document discusses the concepts of capacitance and capacitors. It defines capacitance as the ability of a conductor to store charges, with the capacitance of a conductor being equal to the amount of charge needed to change its potential by 1 volt. A capacitor is formed when two conductors are separated by an insulator. When charged, one plate gains electrons and becomes negatively charged while the other loses electrons and becomes positively charged. The capacitance of a capacitor depends on the size, shape, and distance between its conducting plates as well as the dielectric material between them. Common units of capacitance include the farad and its submultiples like microfarads and picofarads.

It is well divided into 4 portions.
Ultracapacitors
Ultracapacitors store electrical energy electrostatically through polarization of an electrolytic solution at the interface between the electrolyte and electrode, rather than through chemical reactions like batteries. They complement batteries by providing higher power density and longer lifespan than batteries, though lower energy density. Ultracapacitors consist of porous carbon electrodes separated by an electrolyte and membrane, and store energy via ion adsorption at the electrode-electrolyte interface when voltage is applied. They provide rapid charging and discharging compared to batteries.
Class 12th Physics Project File (Capacitors) 23-24
The document summarizes the key aspects of capacitors based on a physics project file submitted by a student. It defines what a capacitor is and discusses how the amount of charge it can store depends on factors like voltage and size. It also describes different types of capacitors like film, ceramic and electrolytic capacitors. Finally, it outlines some common uses of capacitors including energy storage, power conditioning, signal processing, and their use as sensors.
General Physics- Electricity
This document provides an overview of electricity, electric potential, capacitance, and dielectrics. It defines electric potential as the potential energy per unit charge. Capacitance is defined as the ratio of charge on the conductors to the potential difference. Parallel plate capacitors store charge on their plates when connected to a voltage source. Capacitors can be connected in parallel or series, and their equivalent capacitance is calculated. Dielectrics increase capacitance by filling the space between capacitor plates.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Capacitor and principle of capacitors
- 1. Made By :- Vibhu Mehta
- 2. WHAT IS CAPACITORS The capacitor is a component which has the ability or “capacity” to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery.
- 4. Non-polarized Capacitor Polarized Capacitor Variable Capacitor Trimmer Capacitor
- 5. Non-polarized Capacitor Type of capacitor that can be connected any way in a circuit. There is no positive or negative. Common types of non-polar capacitors are ceramic, mica and some electrolytic.
- 6. Polarized Capacitor A capacitor is used with a resistor in a timing circuit. It can also be used as a filter, to block DC signals but pass AC signals.
- 7. Variable Capacitor These are usually made up of one or more moving plates and one or more non moving plates separated by the dielectric. By moving the plates, we can vary the capacitance. And it is used in a radio tuner.
- 8. Trimmer Capacitor This type of variable capacitor is operated with a small screwdriver or similar tool. It is designed to be set when the circuit is made and then left without further adjustment
- 10. As a capacitor is passive component, it does not generate energy. But it is able to store energy from an energy source like a battery or another charged capacitor. When a battery (DC Source) is connected across a capacitor, one surface, named plate I gets positive end of the battery and another surface, named plate II gets negative end of the battery. When battery is connected, the full voltage of that battery is applied across that capacitor. At that situation, plate I is in positive potency with respect to the plate II. Current from the battery tries to flow through this capacitor from its positive plate (plate I) to negative plate (plate II) but cannot flow at max value due to separation of these plates with an insulating material. Rather a very small current will flow through this insulating material (dielectric) from Positive to Negative plate depending upon the value of strength of this dielectric.
- 11. An electric field will form inside the capacitor dielectric from positive to negative plate. As time goes on, positive plate (plate I) will accumulate positive charge from the battery and negative plate (plate II) will accumulate negative charge from negative end of the battery. After a certain time, the capacitor holds maximum amount of charge as per its capacitance with respect to this voltage. This time span is called charging time of this capacitor.
- 12. Now, after removing this battery from this capacitor, these two plates will hold positive and negative charges with respect to a certain voltage level for long time. Thus this capacitor acts as energy source.
- 13. If two ends (plate I and plate II) get shorted through a load, a current will flow through this load from plate I to plate II up to all charges get vanished from both plates. This time span is known as discharging time of the capacitor.
