Question

what do you understand by self inductance. derive an expression of self inductance of a solenoid​

Answer 1

ANSWER

Self inductance is the ratio of induced electromotive force (EMF) across a coil to the rate of change of current through the coil. We denote self inductance or coefficient of with English letter L. According to Lenz's Law, the induced emf opposes the direction of the rate of change of current.

Answer 2

Answer:

Self inductance is defined as the induction of a voltage in a current-carrying wire when the current in the wire itself is changing. In the case of self-inductance, the magnetic field created by a changing current in the circuit itself induces a voltage in the same circuit. Therefore, the voltage is self-induced.
