Question

You are using an electric motor that requires 40 volts to operate. The motor's circuit uses only 5 amps of direct current. How much power is being used?

Answer 1

40 volts multiplicated by 5 amps will give you a total of 200 watts

Answer 2

The simplest formula for electrical power is

Power = (voltage) x (current) .

You stated both of these quantities in the question.

Power = (40 volts) x (5 amperes) = 200 watts .
