A 24-volt DC motor that requires 932.5 watts would draw approximately how many amperes?

Explanation:
Power and current are linked by the equation P = V × I. To find the current, divide the power by the voltage: I = P / V. With 932.5 watts and 24 volts, I ≈ 932.5 / 24 ≈ 38.854 A, which rounds to about 38.9 A. So the motor would draw roughly 38.9 amperes. The other currents would imply different input powers (for example, 15 A would correspond to about 360 W at 24 V), so they don’t match the given wattage. This uses the electrical input power for the approximation.
