    Engineering Solve Motor Coil Current at Startup & Full Speed

    I thought about solving it like this: a) V = Ri -> 120 = 10i -> i = 12 A b) E = V - Ri -> 70 = 120 - 10i -> i = 5 A But I don't know if it's correct

    Engineering Solve Motor Coil Current at Startup & Full Speed

    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...
