Question

what is difrence between self induction and mutual induction any 4?

Answer 1

Distinguish between self-induction and mutual induction. Answer:

Self-Induction Mutual induction

1. Self-Induction is the characteristic of the coil itself. 2. When the main current in the coil decreases, the induced current opposes the decay of current in the coil. 3. When the main current in the coil increases, the induced current opposes the growth of current in the coil. 1. Mutual induction is the characteristic of a pair of coils. 2. When the main current in the coil decreases, induced current developed in the neighbouring coil opposes the decay of current in the coil. 3. When the main current in the coil increases, The induced current developed in the neighbouring coil opposes the growth of current in the coil.

Answer 2

In self inductance, the change in the strength of current in the coil is opposed by the coil itself by inducing an e.m.f. In mutual inductance out of the two coils one coil opposes change in the strength of the current flowing in the other coil.
