What is the basic unit of inductance?

The basic unit of inductance is the henry. Inductance is a property of an electrical component (usually a coil or inductor) that quantifies its ability to store energy in a magnetic field when electric current flows through it. One henry is defined as the amount of inductance that will induce one volt of electromotive force when the current through the inductor changes at a rate of one ampere per second. This relationship is crucial in understanding how inductors behave in AC and DC circuits, and it helps in the design and analysis of electrical systems, including those used in biomedical equipment.

The other choices represent different electrical concepts: hertz is a measure of frequency, the farad is a unit of capacitance, and the mho (the reciprocal of ohm) is a unit of conductance. Each of these units serves distinct purposes in the field of electronics and electrical engineering, but none are relevant to the measurement or definition of inductance.
