An accumulator of emf 2 V and negligible internal resistance is connected across a uniform wire of length 10 m and resistance 30Ω The appropriate terminals of a cell of emf 1.5V and internal resistance 1Ω is connected to one end of the wire and the other terminal of the cell is connected through a sensitive galvanometer to a slider on the wire. What is the length of the wire that will be required to produce zero deflection of the galvanometer? How will the balancing length change? (a) When a coil of resistance 5Ω is placed in series with the accumulator. (b) The cell of 1.5 V is shunted with 5Ω resistor?
