A wire of length L and 3 identical cells is now connected in series with a wire of the same material and cross-section but of length by the same amount `Delta T` in the same time t. the value of N is:-

A wire of length L and 3 identical cells of negligible internal resistance are connected in series. Due to the current, the temperature of the wire is raised by DeltaT in a time t. A number N of similar cells is now connected in series with a wire of the same material and cross-section but of length 2L. The temperature of the wire is raised by the same amount DeltaT in the same time t. the value of N is
