In a circuit which contains inductance (L), as well as resistance (R), such as the one shown in Fig. 4.4.1, when the switch is closed the current does not rise immediately to its steady state value but rises in EXPONENTIAL fashion. This is due to the fact that a BACK EMF is created by the change in current flow.
