An electric motor is being powered with a voltage amplitude of 300 V at 60 Hz . The motor draws a current amplitude of 15.0 A .
A) Find the root-mean-square voltage.
B) Find the root-mean-square voltage.
C) Find the average power consumed by the motor.
Homework Answers
The root-mean-square voltage:
Vrms = Vmax / sqrt(2) = 300 / sqrt(2) = 212.13 V
the root-mean-square current:
Irms = I/sqrt(2) = 15 / sqrt(2) = 10.6 A
the average power consumed by the motor:
Power = Vrms Irms = 212.13*10.6 = 2249.9 W .
