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 T in atime t. A number N of similar cells is now connected in series with a wire of the samematerial and cross-section but of length 2L. The temperature of the wire is raised by thesame amount T in the same time. determine what is The value of N .
