Answer 1

Explanation:

The power dissipated by each resistor can be found using any of the equations relating power to current, voltage, and resistance, since all three are known. Let us use P=V2R P = V 2 R , since each resistor gets full voltage. Thus, P1=V2R1=(12.0 V)21.00 Ω=144 W P 1 = V 2 R 1 = ( 12.0 V ) 2 1.00 Ω = 144 W .
