What emf will be induced in a 10H inductor in which the current changes from 10A to 7A in `9.0 xx 10^(-2)` seconds?

Explanation

To find the induced EMF in a 10 H inductor when the current changes from 10 A to 7 A in a time interval of \(9.0 \times 10^{-2}\) seconds, we can use the formula for induced EMF in an inductor:

\[ \text{EMF} = -L \frac{di}{dt} \]

Where:
- \(L\) is the inductance in henries (H),
