The unit of measure for inductance is the Henry. Inductance is a property of an electrical circuit that quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it.

One Henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force (EMF) of one volt. This relationship highlights the characteristic nature of inductance as it relates the current change and the resulting voltage.

To understand why the other options do not serve as the unit of inductance: Ohm is the unit of resistance, which measures how much a component opposes the flow of electric current. Farad is the unit of capacitance, indicating a capacitor's ability to store electric charge. Volt is the unit of electric potential difference or EMF, measuring the work done to move a charge between two points. Each of these units serves a different function in electrical theory, further emphasizing that Henry is specifically designated for inductance.
