Question

Define self-inductance of a coil. Write its SI unit.

Answer 1

Define self-inductance of a coil.

➡Self induction is that phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself. Self inductance of a coil is defined as the ratio of self-induced emf to the rate of change of current in the coil.

Answer 2

hey mate....

your answer...

it's SI unit is henry(h)

Self-inductance or in other words inductance of the coil is defined as the property of the coil due to which it opposes the change of current flowing through it. Inductance is attained by a coil due to the self-induced emf produced in the coil itself by changing the current flowing through it.
