The unit used to measure inductance is called what?

Explanation:
Inductance is quantified by how much voltage is induced when current changes, so the unit that measures this property is the henry. One henry is defined as the inductance that causes one volt of emf when the current changes at one ampere per second. In practice, you’ll often see smaller values written as millihenries or microhenries, since many inductors in circuits have relatively small inductance. The other units correspond to different electrical properties: the farad for capacitance, the ohm for resistance, and the siemens for conductance. So the unit for inductance is the henry.
