What is the measurement unit for inductance?

Explanation:
Inductance measures how a circuit resists changes in current due to its magnetic field, and its SI unit is the Henry. This unit is defined by the relation V = L (dI/dt): if the current changes at a rate of 1 ampere per second, the induced voltage is 1 volt, so a circuit with inductance of 1 Henry has V = 1 × (dI/dt). The other options belong to different electrical quantities: Farad for capacitance, Joule for energy, and Volt for voltage. So Henry is the correct unit for inductance.
