The mutual inductance between two coils is `2.5 H`. If the current in one coil is changed at the rate of `1 As^(-1)`, what will be the `emf` induced in the other coil?

Explanation

To solve the problem of finding the induced emf in the second coil due to a change in current in the first coil, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Given Data**:
- Mutual inductance (M) = 2.5 H (Henries)
- Rate of change of current (dI/dt) = 1 A/s (Ampere per second)
