Homework Equations
P=IV
I=V/R
P=(V/R)V
R=V^{2}/R
The Attempt at a Solution
P_{R1}: 12^{2}/12=12
P_{R2}: 144/18
I'm not sure what to do from here. Thanks for any input and help!
There you go. Good job.I=V/R
R_{total}=12+18
I=12/30
P_{R1}=RI^{2}
P_{R1}=12*[tex]\frac{2}{5}[/tex]*[tex]\frac{2}{5}[/tex]
P_{R1}=48/25
P_{R2}=[tex]\frac{72}{25}[/tex]=2.88
Thanks!
