The question I'm in doubt about is
The motor coil has a resistance of 10 Ω and is powered by a voltage of 120 V. When the motor is operating at rated speed, its emf is 70 V. Thus, it is questioned:
a) What is the coil current when the motor is started?
b) What is the coil current at rated speed?
What equations can I use to solve it?
