An inductive load draws 5 kW at a power factor of 0.7 from a 240 V, 50-Hz supply. To reduce the kVA demand charge, the consumer decides to connect a capacitor in parallel with the load. Calculate (i) the parallel capacitance C1 that would be required to change the power factor of the total load on the supply to 0.80 lagging and (ii) find the value of the supply current at this power factor.
