What is the unit of measurement for inductance?

Inductance is a fundamental property in electrical circuits that quantifies how effectively a coil or winding can store energy in a magnetic field when an electric current flows through it. The unit of measurement for inductance is the henry.

When a circuit has an inductance of one henry, it indicates that a change in current of one ampere per second will induce an electromotive force (emf) of one volt in the coil. This relationship is central to understanding how inductors operate within electrical systems, including their crucial role in functions like filtering and energy storage in AC circuits.

The other options refer to different electrical measurements: coulombs measure electric charge, farads measure capacitance (the ability of a component to store an electrical charge), and ohms measure resistance in a circuit. Each of these units serves a distinct purpose in electrical theory, but the henry is specifically designated for measuring inductance.
