A device runs on a 36-volt supply and draws 11 amps. What is its power?

Explanation:
Power in a DC circuit is found by multiplying voltage by current. P = V × I. With 36 volts and 11 amps, the power is 36 × 11 = 396 watts. So the correct value is 396 W. For context: 420 watts would need about 11.67 amps at 36 volts; 3960 watts would need 110 amps; 11 watts would require about 0.306 amps.
