An electronic device runs on a 36-volt supply and draws 11 amps. What is the device's power?

Explanation:
Power in an electrical circuit is found by multiplying the voltage by the current. With a 36-volt supply and a current draw of 11 amps, the device’s power is P = 36 V × 11 A = 396 watts. So the 396 W option is the one that matches the given voltage and current. The other numbers would come from different currents (or voltages) than those provided.
