A motor contains a coil with a total resistance of 10 ohms and is supplied by a voltage of 120V. When the motor is running at its maximum speed, the back emf is 70V.
A) What is the current the instant the motor is turned on?
B) What is the current in the coil when the motor has reached maximum speed?
C) Suppose the motor is in a circular saw. While operating the saw, the blade becomes jammed and the motor cannot turn. By what percentage does the power input to the motor increase when it is jammed?
