Calculate the total heat dissipated in a rotor resistor of 14.23 Ω when .65 A current flows through it.

Calculate the total heat dissipated in a rotor resistor of 14.23 Ω when .65 A current flows through it. Correct Answer 6.01 W

The rotor resistor is a linear element. It only absorbs real power and dissipates it in the form of heat. The voltage and current are in the same phase in case of the resistor so the angle between V & I is 90°. P=I2R=.65×.65×14.23=6.01 W.
