The windings of a DC motor have a resistance of 6.00 Ω. The motor operates on 120 V AC, and when running at full speed it generates a back emf of 105 V. What current does the motor draw when operating at full speed?

Question

Quizplus · Accepted Answer

The current drawn by the motor can be calculated using Ohm's Law: I = (V - E) / R, where V is the supply voltage, E is the back emf, and R is the resistance. Substituting the given values: I = (120 V - 105 V) / 6.00 Ω = 2.50 A.
