Induction is measured in which unit?

Explanation:
Inductance is about how much voltage is induced when current changes. The unit Henry quantifies that: V = L di/dt, so 1 henry means a change in current of 1 ampere per second produces 1 volt of induced voltage. Practically, if an inductor has 2 H and the current changes at 3 A/s, the induced voltage is 6 V. The other options measure voltage, resistance, or conductance, not inductance, so they don’t describe the amount of inductance.
