An electrical circuit consisting of a coil with inductance \(L\) and an resistor \(R\) connected in series to the coil. In addition, a voltage source which supplies the voltage \(U_0\) as soon as the circuit is closed with a switch. Then a time dependent current \(I(t)\) flows through the coil and the resistor. The current does not have its maximum value immediately, but increases slowly due to Lenz's law.
