⇒ Since V is not proportional to R therefore, the element can’t be a resistor.
⇒ At t = 5 ms, even if i ≠ 0, the element behaves as a short circuit therefore, the element can’t be a capacitor (since at t = 0 only capacitor behaves as short circuit).
⇒The current at t = 0 is zero and at t = 5 ms voltage across the element is zero therefore, the element must be an inductor (at t = 0, an inductor acts as open circuit and at t =∞ it behaves as short circuit).
From the given voltage and current profile, we have

Since V is not proportional to R therefore the element can't be resistor .
At t = 5 ms, even if i ≠ 0, the element be haves as a short circuit therefore, the element is can't be a capasitor (since at t = 0 onaly capacitor behaves as short curcuit)
At t = 5 ms, even if i ≠ 0, the element be haves as a short circuit therefore, the element is can't be a capasitor (since at t = 0 onaly capacitor behaves as short curcuit)
