Problem 1: [7 Marks] a) A small industrial plant has a 10

Problem 1: [7 Marks] a) A small industrial plant has a 10 kW heating load and a 20 kVA inductive load due to a bank of induction motors. The heating elements are considered purely resistive (Pf=1), and the induction motors have a lagging power factor of 0.7. If the supply is 1000 Vrms at 60 Hz, determine the capacitive element required to raise the power factor to 0.95. b) Compare the levels of current drawn from the supply.
