Homework Statement
Three resistors are connected across a battery as shown in the figure. (Let V = 141 V and R1 = R2 = R3 = 204 Ω.)

(a) How much power is dissipated across the three resistors?
P1 =
P2 =
P3 =
Homework Equations
P=IV
The Attempt at a Solution
I solved for each of the voltages across each resistor. Each resistor is 68 ohms.
so the equivalent resistance of the circuit is 102 = 68 + 1/[2(1/68)]
Using that and the voltage 141 I get the current I = 1.38235 A
Using that I solve for V1 = 94 V and V2 and V3 = 46.999 V
So to get the power for R1 I would take the voltage 94 and multiply it by the current 1.38235 and get 129.9409 W but the answer is incorrect so I'm not sure what I'm doing wrong. The same goes for P2 and P3 when I do the same thing
