Problem

100\,\text{mH}

coil and a

10\,\mu\text{F}

capacitor are connected separately to the same

220\,\text{V}

(rms) AC source. The coil draws

7.0\,\text{A}

50\,\text{Hz}

. At approximately what frequency should the capacitor be operated so that it draws the same rms current as the coil? a)

160\,\text{Hz}

3.2\times10^{3}\,\text{Hz}

510\,\text{Hz}

720\,\text{Hz}
