PHYSICS AB and CD are two uniform resistance wires of lengths 100 cm and 80 cm respectively The connections are shown in the figure The cell of emf 5 V is ideal while the other cell of emf E has internal resistance 2 2 A length of 20 cm of wire CD is balanced by 40 cm of wire AB Find the em E in volt if the reading of the ideal ammeter is 2 A The other connecting wires have negligibl resistance AL Ca 5V 41 40 cm 20 cm www F 2 0 B D A Ammeter ideal
