What is the basic unit of inductance?

The basic unit of inductance is Henry. Inductance is a property of an electrical conductor that quantifies its ability to induce an electromotive force (EMF) in itself or in another conductor due to a change in current. When the current flowing through a conductor changes, it creates a magnetic field around it, and this changing magnetic field can induce a voltage in the conductor. The unit of measurement, Henry, is defined such that one Henry of inductance will induce one volt of EMF when the current through the conductor changes at a rate of one ampere per second.

The other units mentioned relate to different electrical properties. Ohm is the unit of resistance, Volt is the unit of electric potential (voltage), and Farad is the unit of capacitance, which is related to a component's ability to store an electric charge. These are distinct from inductance, which is specifically concerned with the behavior of conductors in relation to magnetic fields and electric current changes.
