What is the SI unit for inductance?

Explanation:
Inductance is measured by how much voltage appears across an inductor for a given rate of change of current. The defining relation is V = L di/dt, so the unit that makes this equation work is the henry. By definition, if the current changes at 1 ampere per second and the voltage across the coil is 1 volt, the inductance is 1 henry. The henry is named after Joseph Henry. The other units correspond to different electrical properties: the farad is for capacitance, the tesla for magnetic flux density, and the weber for magnetic flux. So the unit for inductance is the henry.
