How is inductance measured?

Inductance is measured in henries (H), which is the standard unit for this electrical property. This measurement expresses the ability of a coil to store energy in a magnetic field when electrical current passes through it. The henry is defined based on the relationship between voltage and the rate of change of current through an inductor; specifically, one henry is the inductance of a coil in which a change of current of one ampere per second produces a voltage of one volt across the coil.

Understanding this helps in recognizing the role of inductors in various electrical circuits, where they are used for tasks such as filtering, energy storage, and voltage regulation. The other units mentioned—volts, ohms, and farads—correspond to different electrical properties: volts measure electrical potential, ohms measure resistance, and farads measure capacitance. Thus, measuring inductance accurately requires the specific unit of henries.
