1. The problem statement, all variables and given/known data In this problem we are asked to calculate the total power of the resistors in the circuit below. 2. Relevant equations ##P=I^2R## 3. The attempt at a solution My solution goes like this: PT=PR1+PR2+PR3+PR4+PR5 I can find PR1 and PR5 immediately from the given current generators: PR1=IG1^2*R1 PR5=IG2^2*R5 Since i know those powers one i dont need the current generators and can transform the right and left sides to thevenin equivalents: Clearly ET1=-ET2 ET1=E1=24V and RT1=R1=12Ω (i hope i got this right) Now we can see that we have this type of situation. I transformed the resistor 3 as in the picture and can divide the circuits into 2 and the powers of the resistors will the sum of two. I will be solving the left one: Re=R3R2/(R3+R2)=4Ω I=ET1/(Re+R1) = 24/18 = 4/3 A and the power of two element are P3'+P2=Re*(4/3)^2 and that times 2 is the total power. Something is wrong here. The result should yield 312 W and i just dont get that. What is wrong?
