A motor has coils with a resistance of 28 and operates from a voltage of 235 V. When the motor is operating at its maximum speed, the back emf is 147 V.
(a) Find the current in the coils when the motor is first turned on.
A
(b) Find the current in the coils when the motor has reached maximum speed.
(c) If the current in the motor were 6.0 A at some instant, what is the back emf at that time?
V
