Problem

A capacitor is required to be connected across a 200 V200\,\text V (rms), 60 Hz60\,\text{Hz} AC source so that the rms current does not exceed 1.0 A1.0\,\text A. (a) Calculate the capacitive reactance that will satisfy this condition. (b) Determine the capacitance needed. (c) If the frequency of the source is changed to 100 Hz100\,\text{Hz} while the same capacitor remains connected, find the new rms current in the circuit.
