Four resistors of resistances 1 ohm, 2 ohm, 3 ohm and 4 ohm are connected in the four arms AB, BC, CD and DA of a wheatstone's network. A galvanometer of resistance 5 ohm is connected between B and D. A cell of emf 10 volts and internal resistance 1 ohm is connected between A and C. Find the voltage across the galvanometer. ( USE CRAMER'S RULE TO SLOVE THE PROBLEM)
