13.5 Circuits with Resistors and Inductors (LR Circuits)
BeginnerMCQConceptual21.5k
A schematic diagram of a single-loop series electric circuit rendered as a simple rectangular wire loop. On the left vertical wire is an ideal battery labeled \(\mathcal{E}\), with a long vertical line above a short vertical line. Along the top horizontal wire is an open switch labeled S. On the right vertical wire is a resistor drawn as a standard zigzag line labeled R. Along the bottom horizontal wire is an ideal inductor drawn as four coiled loops labeled L. No other labels, lines, text, or axes appear.
LR circuit connected to a battery.
A circuit contains an ideal battery of potential difference \(\mathcal{E}\), a resistor \(R\), an ideal inductor \(L\), and an open switch, all connected in series. At time \(t = 0\), the switch is closed. Which of the following best explains why the magnitude of the potential difference across the inductor approaches zero as \(t \to \infty\)?
