What is the electrical inductance unit?

Explanation:
Inductance quantifies how much voltage is generated when current changes in a circuit. The unit for this property is the Henry, symbol H. This comes from the relation V = L di/dt: if the current changes at 1 ampere per second and the induced voltage is 1 volt, the inductance L is 1 Henry. In other terms, 1 Henry equals 1 volt-second per ampere, which can also be expressed as ohm-seconds. The other options correspond to different electrical quantities: a Farad is capacitance, a Volt is electrical potential, and an Ohm is resistance.
