A generator supplies a motor rated to 10 kW with a power factor of 0.866 lagging at 110V and 60Hz over a power line with an impedance of 907.5 + j500 m2. A compensating impedance is added in parallel to the motor. What is the required impeandace of the capacitor to draw maximum power from the generator? What is the impedance needed to bring the power factor to 1?
