Question

How much power is produced if a voltage of `8 V` is applied to a circuit with a resistance of `14 Omega`?

Answer 1

power in the circuit= voltage x current
current= voltage divided by Resistance
current=0.571 power= voltage x current=4.5 watts..

Explanation:

Also you can use power is current square x Resistance
0.571 x 0.571x14=.4.5 watts.
