Determine the power dissipated in the 9 ohm resistor in the circuit shown in the drawing. (R1=4.0 Ohms, R2=9.0 Ohms, and V1=9V). When trying to solve this problem, I tired to add the resistance of the bottom two as if they were in series, and then add that to R1 to get the total resistance. I then found the current using the given voltage, and then tried to multiply that to the voltage to get an answer of 9 watts. But that is wrong, and I am not sure where I went wrong. I'd appreciate any help. Thank you.
