What equation calculates the amount of energy stored in an inductor?

The equation that calculates the amount of energy stored in an inductor is given by energy = LI²/2. This formula derives from the fundamental principles of electromagnetic energy storage in inductors. Inductors store energy in their magnetic fields when an electric current flows through them.

In this equation, L represents the inductance of the inductor in henries (H), and I represents the current flowing through it in amperes (A). The energy stored in the inductor is proportional to the square of the current. This indicates that as the current increases, the amount of energy stored rises with the square of that current, highlighting the significance of current in energy storage in magnetic fields.

Using this equation, engineers and technicians can easily calculate how much energy is stored in an inductor for various current levels, essential for analyzing and designing electromagnetically driven systems.
