Finding current and equivalent resistance

  • #1

Homework Statement


The circuit consists of a battery (V0 = 48.0 V) and five resistors (R1 = 111 Ω, R2 = 182 Ω, R3 = 663 Ω, R4 = 334 Ω, and R5 = 465 Ω). Find the current passing through C, D, and G.

V=IR

The Attempt at a Solution


I tried to find the equivalent resistance (Req = 193 Ω). The problem had a hint that said after that, I need to work backwards to find the currents. I understand that C and G will be the sum of the currents at R4 and R5, but I don't know how to find the currents at R4 and R5.

If you know the equivalent resistance of the circuit then you can calculate the
voltage drop across R1. Then you should easily be able to calculate the currents
thru the remaining resistors.
