The document summarizes the results of experiments using a Seebeck electrical generator with two different setups. The first setup used sunlight heating canal water, while the second used glowing charcoal heating tap water. The charcoal-tap water setup produced a higher average voltage of 4.39V compared to 0.35V for the sunlight-canal water setup, due to greater temperature difference. While the sunlight setup could not power a 3V motor, the charcoal setup could. Recommendations included adding more Peltier elements to increase voltage, designing a more strategic heating system, and applying the device to other heat sources.

Electrical Heating - 02-03
Dielectric heating occurs when a non-conducting material is subjected to an alternating electric field, causing dielectric losses that generate heat within the material. The heat generated is proportional to frequency and voltage. Common applications include heating plastics, food processing, and industrial uses like curing and drying. Induction heating uses electromagnetic induction to generate eddy currents within a conductive material, heating it through resistive losses. It can be applied directly by inducing currents in the target material or indirectly by first heating a container that then transfers heat through radiation or convection. Proper selection of frequency allows controlling the heating depth and uniformity.

Electric heating works by converting electrical energy to heat energy using the principle of Joule heating. When an electric current passes through a resistor, it produces heat due to I2R losses. There are various domestic and industrial applications of electric heating, including water heaters, ovens, welding, and heat treatment processes. Electric heating has advantages over other heating methods like being clean, allowing for accurate temperature control, and providing uniform heating. Resistance heating and dielectric heating are two common methods for electric heating. Resistance heating directly or indirectly heats an object by passing a current through it or a nearby resistive element. Dielectric heating generates heat in non-conductive materials using electromagnetic fields.
Space heating
Space heating involves raising interior temperatures through centralized or localized heating systems. Central heating uses a single heat source and distribution system to efficiently heat an entire building. Proper insulation, ventilation, and heat loss calculations are required to control heat flow and minimize energy needs. Common central heating systems use boilers to heat water or air that is circulated through pipes and ducts to radiators, convectors, or underfloor heating for interior warmth.

Thermocouples operate based on the Seebeck effect, where the junction of two different conductors generates a voltage when subjected to a temperature gradient. The voltage is generated along the portion of the conductors experiencing a temperature change, not at the junction itself. The voltage can be approximated based on the Seebeck coefficients of the two materials and the temperatures of the hot and cold junctions. Thermocouples are suitable for temperature measurement over a large range up to 2300°C and are commonly used for industrial processes, though other sensors are better for small temperature changes.

Thermoelectric generation using waste heat
The document discusses thermoelectric generators (TEG). TEGs directly convert temperature differences into electricity through the Seebeck effect. They have applications in power generation from waste heat and in powering small electronic devices like wearable medical sensors. TEGs offer advantages like having no moving parts and being able to extract energy from varied heat sources. However, their efficiency is still relatively low compared to other power generation methods. Research continues toward improving TEG materials and designs to increase their efficiency and potential applications.
Dielectric Heating And Arc Furnace
Dielectric heating employs the polarization effect to heat non-metallic materials. When an alternating electric field is applied, the molecules in the material align with the changing field, causing internal heating through molecular friction. The power loss from the lag between the current and voltage applied to a capacitor is used to heat the dielectric medium. The ease of heating depends on the material's loss factor, which represents power dissipation and is dependent on temperature and electric field strength. Dielectric heating has applications in plastic welding, rubber vulcanization, food processing, and more. An electric arc furnace uses an electric arc to melt scrap metal by forming an arc between graphite electrodes and the charged material.

Hydrogen production using solar energy (PV cell)
This study offers an overview of the technologies for hydrogen production especially alkaline water electrolysis using solar energy. Solar Energy and Hydrogen (energy carrier) are possible replacement options for fossil fuel and its associated problems of availability and high prices which are devastating small, developing, oil-importing economies. But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell temperatures while in operation. Also, hydrogen as an energy carrier must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of carbon dioxide which is harming the environment through global warming. Alkaline water electrolysis is considered to be a basic technique for hydrogen production. In the present study, the effects of electrolyte concentration, solar insolation and space between the pair of electrodes on the amount of hydrogen produced and consequently on the overall electrolysis efficiency are experimentally investigated. The water electrolysis of potassium hydroxide aqueous solution was conducted under atmospheric pressure using stainless steel 316 as electrodes.
The experimental results showed that the performance of alkaline water electrolysis unit is dominated by operational parameters like the electrolyte concentration and the gap between the electrodes. Smaller gaps between the pair of electrodes and was demonstrated to produce higher rates of hydrogen at higher system efficiency

2. e.m.f sources & effects of current
This document outlines a unit on electrical science principles. It identifies three main sources of electromotive force: magnetic, chemical, and thermal. Magnetic force is generated by rotating a coil in a magnetic field, producing alternating current. Chemical sources include batteries and cells, where two dissimilar metals and an electrolyte produce direct current. Thermal sources use the Seebeck effect where applying heat to connected dissimilar metals produces voltage. Effects of electric current include heating, chemical changes through electrolysis, and generating magnetic fields around conductors.
Types of chemical Batteries & its function.ppt
Batteries convert chemical energy into electrical energy through redox reactions. They are made up of voltaic cells, which contain two different metals serving as electrodes and an electrolyte solution. In a voltaic cell, the anode metal oxidizes and releases electrons that flow through an external circuit to the cathode, where they reduce the metal ions in solution. The voltage produced depends on the standard reduction potentials of the two metals. Connecting multiple cells in series increases the overall voltage output. Different electrode combinations can produce different voltages, with lithium and fluorine theoretically providing the highest voltage. Environmental concerns include hazardous materials in some battery components and pollution if batteries are not properly recycled.

Potato_Battery.pdf
This document describes how to build a potato battery and discusses some key concepts about batteries and electrochemistry. It explains that a potato battery uses a potato as an electrolyte and zinc and copper electrodes to drive an oxidation-reduction reaction. Voltage and current from the battery can be measured with a multimeter. Connecting multiple batteries in series increases voltage but not current, while connecting in parallel increases current but not voltage. The document provides instructions and data for a potato battery experiment.
KRISHNA'S THERMOEMF IMPLEMENTATION
The document proposes using the exhaust heat from an internal combustion engine to charge a battery through the Seebeck effect. Thermoelectric modules made of dissimilar metals would harness the temperature difference between the hot exhaust manifold (around 250°C) and cooler atmosphere (25°C) to generate voltage. An induction coil and inverter would amplify and convert the direct current to charge the battery, effectively utilizing wasted heat. Calculations estimate a thermoelectric module of 50 couples could produce 0.47 volts, and over 600 couples would be needed to generate 6 volts for battery charging. The design aims to provide an alternative energy source while reducing exhaust temperature emissions.
Transformers.pptx
A transformer transfers electrical energy between circuits through electromagnetic induction. It consists of two coils wound around an iron core. An alternating current applied to one coil induces a voltage in the other coil.
The key components are the primary and secondary coils, the magnetic core, and insulation between the coils. The core is made of thin iron laminations to reduce eddy currents. Copper losses from resistance heating vary with load current, while core losses from hysteresis are constant.
Efficiency is maximized when copper and core losses are equal. Maximum efficiency occurs at a load that is the ratio of core to copper losses, and is independent of power factor. Voltage regulation is the change in output voltage from no-load to full
Tti presentation_basic electricity level 1

Key topics covered include the composition of matter, electrical magnitudes and their units, direct and alternating current, resistance, series and parallel circuits, magnetism, batteries, alternators, starters, and troubleshooting faults. The course aims to familiarize students with electrical concepts and components through exercises and hands-on learning over the duration of two days.
Electrical Heating 02-02
Dielectric heating occurs when a non-conducting material is subjected to an alternating electric field, causing dielectric losses that generate heat within the material. The heat generated is proportional to frequency and voltage. Common applications include heating plastics, food processing, and industrial uses like curing and drying. Induction heating uses electromagnetic induction to generate eddy currents within a conductive material, heating it through resistive losses. It can be applied directly by inducing currents in the target material or indirectly by first heating a container that then transfers heat through radiation or convection. Proper selection of frequency allows controlling the heating depth and uniformity.
Transformer Failure Due to Circuit Breaker Induced Switching Transients
This document summarizes several case studies of transformer failures caused by circuit breaker induced switching transients. It describes how the current chopping and re-strike characteristics of vacuum and SF6 circuit breakers can cause high voltage surges when switching inductive loads like transformers. Several examples are given of transformer failures on energization or de-energization where the contributing factors included short cable lengths and dry-type transformers. Graphs from EMTP modeling show the reduction in surge voltages that can be achieved by installing RC snubbers on the transformer primary. The document recommends mitigation techniques like arresters, surge capacitors, snubbers or their combination to reduce switching transient overvoltages.

JIE_hybrid_PVT_model
Sameer Simms presented a dynamic numerical model of a 2D hybrid photovoltaic-thermal (PVT) panel. The model simulated the performance of both a PVT panel and a standard PV panel under controlled and real weather conditions. The results showed that the PVT panel operated at lower temperatures than the PV panel, leading to 13.5% higher electricity generation. While the PVT panel produced more thermal power than electrical power, the total thermal energy was low due to heat losses during periods of low sunlight. Future work will focus on validating the model, upgrading it to 3D, and reducing simulation times.
The Sun !!!
The document describes a low voltage generator called "The Sun" that was created by three students for a class. The generator can produce 5 to 120 volts of power using solar panels, batteries, and other electrical components. It uses a breadboard, micro USB ports, solar panels, batteries, voltage regulators, capacitors, and other parts to receive direct current from batteries and solar panels and regulate it to a constant 5 volt output through three USB ports.
Effect of temperature on the performance of a closed-cycle ocean thermal ener...
Ocean Thermal Energy Conversion (OTEC) is a process that can produce electricity by using the temperature difference between deep cold ocean water and warm tropical surface waters. OTEC pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity. There are 3 types of OTEC systems which are closed-cycle, open-cycle, and hybrid cycle. Solar thermal collector is used to heat up a fluid. Generally for water or a mixture of glycol and water depending of the configuration of the solar thermal system. The principles are to capture solar radiation, converting it to useful heat and transferring it to a working fluid.
KRISHNA THERMOEMF IMPLEMENTATION
1) The document presents a method for using the exhaust heat from an internal combustion engine to charge a battery through the Seebeck effect. Thermoelectric modules placed in the engine exhaust produce voltage when exposed to temperature differences that is then amplified and used to charge the battery.
2) The exhaust manifold material acts as the hot junction at around 250°C, while the atmospheric temperature of 25°C acts as the cold junction, creating a temperature difference to generate thermoelectric voltage through the Seebeck effect.
3) Calculations show that arranging 50 thermocouples in series could produce around 0.47 volts of voltage, which when amplified could provide over 90 watts of power to charge the battery.

The mechanism of electronic ballast
This document summarizes the key components and operating principles of fluorescent lamps and ballasts. It explains that fluorescent lamps are more efficient than incandescent, last longer, and operate cooler. The lamp contains mercury vapor, phosphor coating, and electrodes. It requires a ballast to start through a high voltage excitation and then regulate the current. Modern high frequency electronic ballasts are more efficient and compact than magnetic ballasts, using half-bridge circuits or self-oscillating designs to start and regulate the lamp.

- 3. Statement of the Problem
- 8. Methodology
- 11. MATERIALS
- 24. Characterization
- 25. Device Making
- 36. Problem 1 A. The average amount of voltage produced in the Sunlight-Canal water set-up was 0.35 V. B. The average amount of voltage produce in the Charcoal-Tap water set-up was 4.39 V.
- 37. Therefore, Seebeck Electrical Generator produced electricity through the temperature difference of canal water and ambient temperature exposed to sunlight and tap water and glowing charcoal.
- 38. Problem 2 The recorded voltages in each set-up were the following: A. Sunlight-Canal Water Set-up: • Minimum voltage: 0.23 V • Maximum voltage: 0.46 V • Mean voltage produced: 0.35V B. Charcoal-Tap Water Set-up • Minimum voltage: 3.56 V • Maximum voltage: 5.02 V • Mean voltage produced: 4.39 V
- 39. Only minimal amount of voltage was released in the Sunlight-Canal Water Set-up due to the inconsistency of the heat of the sun as the source of energy of the Seebeck Electrical Generator. A large amount of voltage was released in the Charcoal-Tap Water Set-up because of a high temperature difference.
- 40. Problem 3 The Sunlight-Canal water set-up only produced a mean voltage of 0.35 V. (Cannot power a 3 V DC Motor) In the Charcoal-Tap water set-up, the total mean voltage produced was 4.39 V. (Can power a 3 V DC Motor)
- 41. The Seebeck Electrical Generator has the capacity to power a 3 V DC motor given a high temperature difference from the sources.
- 42. Recommendations More Peltier elements should be added to the SEG. (Increase in the number of Peltier elements will increase the amount of voltage produced)
- 43. Recommendations Devise a more strategic set-up – considering the location, weather and the like.
- 44. Recommendations The galvanized iron should be mobile to harness more energy from the sun wherever it faces without having the need to move the device.
- 45. Recommendations The device should be applied to heat-emitting apparatuses such as stoves, grillers, engines, machines and the like to take advantage of heat—the waste energy.
- 46. THANK YOU!
