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 ΔT in a time t. A number of N similar cells are now connected in series with a wire of the same material and area of cross-section but of length 2L. The temperature of the wire is raised by the same amount ΔT in the same time. Find the value of N.
    Correct answer is '6'. Can you explain this answer?

    In the first case,
    (3E)2 / Rt = msΔT ... (i)
    When the length of the wire is doubled, resistance and mass both are doubled. Therefore, in the second case,
    (NE)2 / 2R x t = (2m)sΔT ... (ii)
    Dividing Eq.(ii) by (i) we get,
    N2 / 18 = 2
    or N2 = 36
    or N = 6
