Can an inductor have potential difference across it ends even if does not store any energy.

Explanation

To determine if an inductor can have a potential difference across its ends even if it does not store any energy, we can analyze the behavior of inductors in relation to current and electromagnetic induction.

### Step-by-Step Solution:

1. **Understanding Inductance**: An inductor is a passive electrical component that stores energy in its magnetic field when current flows through it. The potential difference (voltage) across an inductor is related to the rate of change of current through it.

2. **Formula for Back EMF**: The potential difference (back EMF) across an inductor is given by the formula:
\[
