Question

How much power is produced if a voltage of `6 V` is applied to a circuit with a resistance of `72 Omega`?

Answer 1

First find current current= voltage divided by Resistance.

Explanation:

6/72= 0.08333. power is current squared x resistance.
0.08333x 0.083333==0.0069444.
power 0.006944 x 72=.4999 watts.
