What is the unit of measurement for inductance?

Inductance is measured in henrys, which is the standard unit used to define how effectively an inductor can store energy in a magnetic field. One henry is defined as the amount of inductance required to produce an electromotive force (emf) of one volt when the current through the inductor is changing at a rate of one ampere per second. This relationship is crucial in understanding how inductors operate in electrical circuits, particularly in AC applications, where they react to changes in current.

The other options represent different electrical units: volts measure electric potential, farads measure capacitance, and watts measure power. Each of these has distinct characteristics that apply to different components and phenomena in electrical theory and practice, but they do not measure inductance.
