Question

What is the use of inductance?

Answer 1

To store electrical energy in the form of a magnetic field.  To create an electromagnetic field around the inductor to be used in relays and solenoids.

To provide resistance dependant on frequency, in a circuit.  This allows for the construction of filters for signals to filter out unwanted frequency components of those signals.

.

Answer 2

* To create magnetic fields (Motors, transformers, induction heating)

* To limit AC current (coke coils)

* To filter out H.F. signals

Answer 3

It is used as filter in the power circuits.
