Problem

The current in a primary coil varies with time according to

I = 4 \sin(200π t)\,\text{A}

. If the mutual inductance between the primary and secondary is

0.25\,\text{H}

, the maximum value of the emf induced in the secondary is a)

3.1 \times 10^{2}\,\text{V}

2.0 \times 10^{2}\,\text{V}

6.3 \times 10^{2}\,\text{V}

4.4 \times 10^{2}\,\text{V}
