# An ideal LC circuit consists of a \(25\text{ }\mu\text{F}\) capacitor connected in series with a \(40\text{ mH}\) inductor and an open switch. The capacitor is initially charged to a potential difference of \(24\text{ V}\), and the initial current in the circuit is zero. The switch is closed at time \(t = 0\), allowing the circuit to oscillate. What is the maximum current that flows through the inductor during the subsequent oscillations?

![A schematic diagram showing a single rectangular circuit loop oriented horizontally. The left vertical branch contains a capacitor labeled C = 25 \mu\text{F}. The right vertical branch contains an inductor drawn as four adjacent semicircular loops, labeled L = 40\text{ mH}. The top horizontal branch contains an open single-pole single-throw switch labeled S. The bottom branch is a continuous straight horizontal wire. All connecting wires are drawn as solid black lines forming a closed rectangular path except at the open switch. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-circuit-1-1787461188-49ZsMT.jpg)
