The unit of inductance, the henry, is defined as the amount of self-induced electromotive force (emf) in a circuit when the current in the circuit changes at a rate of one ampere per second. This can be mathematically expressed as emf = L(di/dt), where L is the inductance in henrys, i is the current in amperes, and di/dt is the rate of change of current in amperes per second. Therefore, we can rewrite the equation as L = emf/(di/dt) = V·s/A, which shows that the unit of inductance is equivalent to volts·seconds per ampere (V·s/A).
