Question

derive an expression for electric energy consumed in a device in terms of v, i and t, where v is thepotential difference applied to it, i is the current drawn by it and t is the time for which the current flows

Answer 1

energy = power × time
power in electric circuit is equals to current(i) multiply voltage or potential difference(v)
so energy = VI × t
