356889 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 \({\Delta T}\) 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 \({2 L}\). The temperature of the wire is raised by the same amount \({\Delta T}\) in the same time \({t}\), find the value of \({N}\) is
