Current Electricity

Consider an electrical conductor connected across a potential difference \(V\). Let \(\Delta q\) be a small charge moving through it in time \(\Delta t\). If \(I\) is the electric current through it,

I. the kinetic energy of the charge increases by \(I V \Delta t\).

II. the electric potential energy of the charge decreases by \(I V \Delta t\).

III. the thermal energy of the conductor increases by \(I V \Delta t\).

Choose the correct option.
