Parallel Resonance Circuit
A parallel circuit containing a resistance, R, an inductance, L and a capacitance, C will produce a parallel resonance (also called anti-resonance) circuit when the resultant current through the parallel combination is in phase with the supply voltage. At resonance there will be a large circulating current between the inductor and the capacitor due to the energy of …

Solved An industrial load consisting of a bank of induction
An industrial load consisting of a bank of induction motors consumes 50 kW at a power factor of 0. 8 lagging from a 220-V, 60-Hz, single-phase source. By placing a bank of capacitors in parallel with the load, the resultant power factor is to be raised to 0. 95 lagging. Find the net capacitance of the capacitor bank in mu F that is required.
