A current of 10A in the primary of a circuit is reduced to zero at a uniform rate in `10^(-3)` sec. If the coefficient of mutual inductance is 3 henry, what is the induced emf?

Explanation

To solve the problem step by step, we will use the formula for induced electromotive force (emf) in a coil due to a change in current in a nearby coil, which is given by:

\[ E = -M \frac{di}{dt} \]

Where:
- \( E \) is the induced emf,
