What unit is used to measure inductance?

The unit used to measure inductance is the Henry. Inductance is a property of an electrical component, typically a coil or inductor, that quantifies its ability to store energy in a magnetic field when an electric current passes through it. The measurement of inductance relates directly to how much voltage is induced across the inductor when the current flowing through it changes.

One Henry is defined as the inductance that produces an electromotive force of one volt when the current through the inductor changes at the rate of one ampere per second. This foundational relationship forms the basis of understanding inductors in circuits and their behavior under varying electrical conditions. In this context, the Henry is essential in both theoretical and practical applications within electronics and electrical engineering.
