A straight cylindrical wire of length \(L\) carries a constant electric current \(I\). The current is due to free electrons, each having mass \(m_e\) and charge of magnitude \(e\), moving along the wire with an average drift speed \(v_d\). Which of the following expressions represents the total kinetic energy of all free electrons within this length \(L\) of the wire?
