A long, thin copper wire of radius r and length L has an electrical resistance of ρ per unit length. The wire is initially kept at a room temperature of T_a and subjected to an electric current flow of I . The heat generation due to the current flow is simultaneously lost to the ambient by convection. Set up an equation to determine the temperature of the wire as a function of time. Mention the assumptions made in the derivation of the equation.
