Homework Statement
AB, BC and CD are three resistors connected together at B and C. AB = 12 ohms, BC = 7 ohms, CD = 6 ohms. A battery of emf 48V and internal resistance 0.5 ohms has it positive pole connected to B and its negative connected to D. A battery of emf 74V and internal resistance 1 ohm has its positive pole connected to A and its negative pole connected to C. Find the current flowing in BC.
Homework Equations
E = I(R +r)
V = IR
The Attempt at a Solution
To be honest, I'm clueless.
I tried using E = I(R + r) but unsure how to add up resistors in a triangle :S
