Problem

The magnetic flux through a 15-turn coil increases uniformly from

0

2.0\times10^{-3}\,\text{Wb}

0.10\,\text{s}

. The coil’s total resistance is

3.0\,\Omega

. What is the average power dissipated in the coil during this interval? a)

6.0\times10^{-2}\,\text{W}

1.5\times10^{-2}\,\text{W}

3.0\times10^{-2}\,\text{W}

4.5\times10^{-2}\,\text{W}
