A wire of length L and 3 identical cells of negligible internal resistances are connected in series. Due to the current, the temperature of the wire is raised by ΔT 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 the length 2 L. The temperature of the wire is raised by the same amount ΔT in the same t. The value of N is
