Question
I need the answer quickly
a. A small industrial plant has a 10 kW heating load and a 20 kVA in-
ductive load due to a bank of induction motors. The heating elements
are considered purely resistive (F, = 1), and the induction motors have
a lagging power factor of 0.7. If the supply is 1000 V at 60 Hz, deter-
mine the capacitive element required to raise the power factor to 0.95.
b. Compare the levels of current drawn from the supply.
