Problem

In a Wheatstone bridge, R1=100  ΩR_1 = 100\;\Omega, R2=200  ΩR_2 = 200\;\Omega, R3=300  ΩR_3 = 300\;\Omega, and R4=600  ΩR_4 = 600\;\Omega. A battery of EMF E=12  V\mathcal{E} = 12\;\text{V} (negligible internal resistance) is connected across one diagonal. Is the bridge balanced? If so, find the current through each resistor.
