The current in a coil decreases from 1 A to 0.2 A. In 10sec. Calculate the coefficient of self inductance. If induced emf is 0.4 volt.
Text Solution
Verified by ExpertsThe correct answer is:
A
emf induced in the circuit is directly proportional to the rate of change of current. emf induced 
rate of change of current i.e., 
when the proportionality constant is removed, the some constant 
comes here.
Hence, 
Given,
