Question:

Consider a motor rated 840 W with 70% power factor operating from a 120 V, 60 Hz, one-phase source. Determine

(a) The source current if a 308 μF capacitor is added to the motor in series

(b) The value of the capacitance that must be placed in parallel with the motor to increase the overall power factor to unity

(c) The source current in the case of (b).

Conclude on the benefits of improving the power factor.
