Question

Determine how much power would be consumed in a parallel circuit that has a source voltage of 300 volts and a total circuit current of 4.2 amps.

Help please

Answer 1

1260 W

Explanation:

You want the power supplied by a 300 V source at a current of 4.2 amperes.

Power

The source power being supplied is the product of its voltage and current:

P = VI

P = (300 V)(4.2 A) = 1260 W

The circuit is consuming 1260 watts.
