KCET 2021 Physics Solved Paper

Consider an electrical conductor connected across a potential difference V. Let Δq be a small charge moving through it in time Δt. If I is the electric current through it,
I. the kinctie energy of the charge increases by IV‌Δ‌t.
II. the electric potential energy of the charge decreases by IV‌Δ‌I.
III. the thermal energy of the conductor increases by IV‌Δ‌t.
Choose the correct option.
