Consider the electric circuit $K$ consisting of:
- a resistance $R$
- an inductance $L$
in series with a source of electromotive force $E$ which is a function of time $t$.
Let the electric current flowing in $K$ at time $t = 0$ be $I_0$.
Let a constant EMF $E_0$ be imposed upon $K$ at time $t = 0$.
The electric current $I$ in $K$ is given by the equation:
- $I = \dfrac {E_0} R + \paren {I_0 - \dfrac {E_0} R} e^{-R t / L}$
The term $\dfrac {E_0} R$ is known as the steady-state part of $(1)$.
