A motor with power factor 0.6 draws 4200 W of real power at 240 V from 10 kVA transformer. Suppose a second motor is needed and it too draws 4200 W. With both motors on line, the transformer will be overloaded unless a power factor correction can be made.

a. What power factor would be needed to be able to continue to use the same 10-kVA transformer?
b. How many kVAR would need to be added to provide the needed power factor?
c. How much capacitance would be needed to provide the kVAR correction?
