Problem

An inductor of

0.50\,\text{H}

and a resistor of

10\,\Omega

are connected in series with a

50\,\text{V (rms)}

50\,\text{Hz}

ac source. To obtain the maximum current, you may insert a

20\,\mu\text{F}

capacitor, an

80\,\mu\text{F}

capacitor, or both capacitors connected in parallel. Which option results in the greatest current at

50\,\text{Hz}

? a) only the

80\,\mu\text{F}

capacitor inserted b) both capacitors connected in parallel inserted c) only the

20\,\mu\text{F}

capacitor inserted d) no capacitor inserted
