PHYSICS AB and CD are two uniform resistance wires of

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
