A 270-V rms 80-Hz supply serves a load that is 12 kW, 17 KVAR (capacitive), and 25 KVAR (inductive). Find: (a) the apparent power (b) the current drawn from the supply (c) the KVAR rating and capacitance required to improve the power factor to 0.96 lagging (d) the current drawn from the supply under the new power-factor conditions
