Question # 1
Define electromagnetic induction.
- Ans 1: When a conductor is moved through a magnetic field,the electric current flow through the circuit,The emf produced in the conductor is called induced emf,and the current generated is called induced current.This phenomena is known as electromagnetic induction.

Question # 1
What is the working principle of transformer?Explain
- Ans 1: The transformer work on the principle of mutual induction between two coils.The transformer consists of two coils of copper electrically insulated from each other,wound on the same iron core,The coil to which AC power is supplied is called primary and that from which power is delivered to the circuit is called secondary.

Question # 1
Name the factor upon which the self inductance depends.
- Ans 1: It depends upon induced emd and time rate of change of current in the coil.It also depend upon the number of turns of the coil,its area of cross section and the core material.
