Question:

A capacitor is connected across the terminals of a 110 V rms, 60.0 Hz generator. For what capacitance is the rms current 2.8 mA?

Capacitive AC Circuit:

When a capacitor is connected to the AC circuit, the charging and discharging cycle sets in, to cause phase difference between the voltage and the current. The capacitive reactance depends on the frequency of AC.

Given Data

  • RMS voltage of the source, {eq}V_{rms}\ = 110\ \text{V} {/eq}
  • frequency of Ac source, {eq}f\ = 60.0\ \text{Hz} {/eq}
  • RMS current,...
