WebBy substituting Ohm’s law V = I R V = I R into Joule’s law, we get the power dissipated by the first resistor as P 1 = I 2R1 =(0.600 A)2(1.00 Ω)= 0.360W. P 1 = I 2 R 1 = ( 0.600 A) 2 ( 1.00 Ω) = 0.360 W. Similarly, P 2 = I 2R2 = (0.600 A)2(6.00 Ω)= 2.16W P 2 = I 2 R 2 = ( 0.600 A) 2 ( 6.00 Ω) = 2.16 W and P 3 = I 2R3 = (0.600 A)2(13.0 Ω)= 4.68W.
