Whenever a conductor is placed in a varying magnetic field, EMF is induced in the conductor and this EMF is called induced EMF.

First Law of Faraday's Electromagnetic Induction state that whenever a conductor are placed in a varying magnetic field emf are induced which is called induced emf,

When a length of wire is formed into a coil, as shown in Figure 1, it becomes a basic inductor. The terms coil and inductor are used interchangeably.

A Small Electronics Dictionary Explaining some of the basic phrases used in electronics

Any charge has the potential to do the work of moving another charge, by either attraction or repulsion.

Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow.

Charles coulomb formulated two laws on the bases of experiments, which are known as electrostatic laws, or coulomb laws of electrostatic.

Capacitors store electric charge. They are used with resistors in timing circuits because it takes time for a capacitor to fill with charge.

In the branch current method Kirchhoff's voltage and current laws are used to solve for the current in each branch of a circuit.

Atom consists of three particles electrons, protons and neutrons. Electrons revolve around a nucleus which consist of neutron's proton's.
