A 5kVA motor operates from a 240V 50Hz supply at a lagging p.f. of 0.6 and is in parallel with a heating and lighting load of 3kW. What is the overall p.f. and what capacitance is required to improve this to 0.95 lagging? What is the apparent power before and after correction? What is the total current flow before and after correction?
