The electric motor operates under a voltage of 120 V. The motor power is 20 kW. Determine the magnitude of the motor current.
These tasks: U (voltage under which the taken electric motor operates) = 120 V; P (motor power) = 20 kW (20 * 10 ^ 3 W).
We express the magnitude of the current in the electric motor from the formula: P = U * I, whence I = P / U.
Calculation: I = 20 * 10 ^ 3/120 ≈ 167 A.
Answer: A current of 167 A flows through the electric motor.
