CBSE Class 12-science Answered

Three identical cells, each of emf 2 V and internal resistance 0.2 ohm are connected in series to an external resistor of 5.4 ohm. Calculate the current in the circuit.

Expert Answer

Net emf of the cell = 3 x 2 = 6 V

Total resistance of the circuit = 0.2 + 0.2 + 0.2 + 5.4 = 6 ohm
