The unit of inductance, henry (H), plays a crucial role in determining the amount of energy stored. Energy storage capability of an inductor depends on both its inductance and the square of the current passing through it. In AC circuits, inductors can temporarily store and release energy, causing phase shifts between voltage and current.
