Semiconductors
Semiconductors are substances that can conduct electricity under some conditions but not others. They have resistivity between metals and insulators. There are two types - elemental semiconductors consisting of a single element like silicon or germanium, and compound semiconductors consisting of multiple elements like indium phosphide. In semiconductors, energy levels split into permitted energy bands separated by a forbidden energy gap when atoms are close together. The valence band is filled with electrons and the conduction band above it is empty or partially filled, with a gap between them through which electrons need energy to move.
Semiconductor Devices Class 12 Part-1
This document discusses energy bands in solids and semiconductor devices. It explains how the discrete energy levels in isolated atoms merge and form continuous energy bands as atoms are brought together in a solid. In semiconductors, the valence band is full while the conduction band is empty, with a small band gap between them. Thermally excited electrons can cross this gap, making semiconductors weakly conductive. Doping a semiconductor with impurities introduces donors or acceptors that increase the number of free electrons or holes, making it an n-type or p-type extrinsic semiconductor. The carrier concentrations and conductivity of semiconductors are determined by factors like doping level, temperature, and carrier mobilities.

The document discusses the structure of atoms. It explains that atoms are made up of subatomic particles like electrons, protons, and neutrons. J.J. Thomson discovered the electron, while E. Goldstein discovered the positively charged particle, which was later named the proton.

Electrodynamics
There are two types of electrical generators - AC and DC generators. AC generators, also called alternators, convert mechanical energy into alternating electrical energy, while DC generators produce direct current. Electric motors operate by using a current in a loop of conductor to generate opposing Lorentz forces on opposite sides of the loop, causing the loop to rotate. Alternating current has a root mean square (RMS) value which is the maximum value divided by the square root of two and is used to calculate average power in a resistive circuit with AC.

Collision processes, mobility of ions and electrons, diffusion, and mean free path are also discussed. The document further explains the ionization process and Townsend's criteria for electrical breakdown in gases.
ELECTRICITY PROJECT
Electricity is associated with stationary or moving electric charges borne by elementary particles like electrons. Various manifestations of electricity result from the accumulation or motion of electrons. Key historical figures involved in the study and advancement of electricity include Thales, William Gilbert, Thomas Browne, Benjamin Franklin, Alessandro Volta, Michael Faraday, and Thomas Edison.

Chapter 02- Breakdown in Gases (part-2)
This document provides a summary of key concepts regarding electrical breakdown and conduction in gases:
- Gases can act as insulating or conducting media depending on the applied voltage. Low voltages allow small currents, while higher voltages cause electrical breakdown through ionization processes.
- Breakdown occurs through the formation of a conductive spark between electrodes. It involves transitions from non-sustaining to self-sustaining discharges.
- Ionization processes like collisional ionization and photoionization generate free electrons and ions, leading to current growth. Secondary processes like positive ion bombardment and photon emission further sustain the discharge.
- The Townsend theory and streamer theory describe the mechanisms of breakdown under different conditions involving
electricity checkpoint F2 2020.pptx
- Electricity is the flow of electric charges, namely electrons. Electric current occurs when electrons flow through a conductor in a complete circuit due to an applied voltage or electric pressure.
- Resistance opposes the flow of electrons and is measured in Ohms. Resistance causes some of the electrical energy to be converted to thermal energy and light. Factors like material type and dimensions affect resistance.
- Ohm's Law states that voltage equals current times resistance (V=IR). In a series circuit there is only one path for current, while in a parallel circuit there are multiple branches for current.

It then discusses the torque on a bar magnet in a magnetic field and two magnets suspended freely and perpendicular to each other. The document explains that the origin of magnetism in materials comes from the electron revolving around the nucleus, which creates a magnetic dipole moment. It also discusses the magnetic moment of an electron and how it is proportional to the orbital angular momentum. Finally, it covers the concepts of magnetization and how it relates to the net magnetic field inside a solenoid.
Chap 11 - ELECTRIC CURRENT THROUGH CONDUCTOR.pptx
This document discusses electric current through conductors. It begins by defining electric current as the rate of flow of electric charge. In metallic conductors like wires, electric current is carried by the flow of electrons. When a large number of metal atoms come together, their valence electrons become delocalized and free to move throughout the material as conduction electrons.
When a potential difference is applied across a conductor, the conduction electrons begin to drift in the direction of the applied electric field at a constant drift speed. This drift of electrons constitutes an electric current. Ohm's law establishes the direct proportional relationship between current and applied potential difference for many materials when their physical state remains unchanged. The proportionality constant is the resistance of the material.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
