Ask Your Teacher A coil has an inductance of 3.00 mH, and the current in it changes from 0.200 A to 1.50 A in a time interval of 0.200 s. Find the magnitude of the average induced emf in the coil during this time interval.

Magnitude of the average induced emf in the coil Volts

Explanation:

Induced emf in a coil with current flowing through it is can be calculated using the relation given below

------------ Equation (1)

Where "L" represents the inductance in H

dI represents the change in current in Ampere

and dt represents the change in time or time period for which the current is flowing in seconds

Given

mH   H

Ampere

Ampere

seconds

Substituting the given values in equation (1) we get -
