## Electricity & Magnetism (Nasir Pervaiz Butt)

BSc/BS notes on Electricity and Magnetism is given below. These notes will help you understand Electricity and Magnetism very easily.

Electrostatics

Coulomb's law or Coulomb's inverse-square law is a law of physics describing the electrostatic interaction between electrically charged particles…read more and download.

Electric Field

An electric field is the region of space surrounding electrically charged particles and time-varying magnetic fields…read more and download

Electric Potential

The electric potential at a point is equal to the electric potential energy of a charged particle at that location divided by the charge of the particle…read more and download

Capacitance & Dilectrics

Capacitance is the ability of a body to store an electrical charge and a dielectric is an electrical insulator that can be polarized by an applied electric field…read more and download

Current and Resistance

Electric current is a flow of electric charge through a medium and electrical resistance of an electrical element is the opposition to the passage of an electric current through that element…read more and download

DC Circuits

A DC circuit (Direct Current circuit) is an electrical circuit that consists of any combination of constant voltage sources, constant current sources, and resistors…read more and download

Magnetic Field Effects

A magnetic field may be represented by a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field…read more and download

Ampere's Law

In classical electromagnetism, Ampère's circuital law, discovered by André-Marie Ampère in 1826,relates the integrated magnetic field around a closed loop to the electric current passing through the loop…read more and download

Fraday's Law of Electromagnetic Induction

Faraday's law of induction dates from the 1830s, and is a basic law of electromagnetism relating to the operating principles of transformers, inductors, and many types of electrical motors and generators…read more and download

Inductance

In electromagnetism and electronics, inductance is that property of a circuit by which a change in current in the circuit “induces” a voltage (electromotive force) in both the circuit itself (self-inductance) and any nearby circuits (mutual inductance)…read more and download

AC Circuits

An AC circuit (Alternating Current circuit) is an electrical circuit that consists of any combination of alternating voltage sources, alternating current sources, resistors and inductors…read more and download
