1. The problem statement, all variables and given/known data http://img130.imageshack.us/img130/2366/capturewvb.jpg" [Broken] 2. Relevant equations V=IR 3. The attempt at a solution Given Information V I R Battery R1 12 V 2 ohm R2 4 ohm R3 24 V 4 ohm R4 8 ohm I can calculate the current of R1 V = IR I = V/R I = 12 V/2 = 6 A = I1 pl if i'm correct sense R1 and R2 are in parrallel and right next to the battery they should share the same voltage? R2 = 12 V from which I can calculate the current V = IR I = V/R = 12 V / 4 ohm = 3 A = I2 now the current for the whole batter should just be I1 + I2? = 6 A + 3 A = 9 A = I battery I can fidn the R battery by doing (1/R1 + 1/R2)^-1 + (1/R3 + 1/R4)^-1 = (1/2 + 1/4)^-1 + (1/4 + 1/8)^-1 = 4 ohm = R battery am i doing this right were do i go from here?
