The current through an inductance follows an exponential growth when the voltage is applied, or exponential decay when the voltage is removed, before reaching a steady state. Inductors resist changes in current, so it takes time for the current to build up or die down, with the rate of change dictated by the inductance (L) and the resistance (R) of the circuit via the time constant (τ = L/R).
The current through an inductance follows ______?
