Q .     For the LCR circuit, shown here, the current is observed to lead the applied voltage. An additional capacitor `C'`, when joined with the capacitor `C` present in the circuit, makes the power factor of the circuit unity. The capacitor `C'`, must have been connected in parallel with `C` and has a magnitued
