13.6 Circuits with Capacitors and Inductors (LC Circuits)

Describe the physical and electrical properties of a circuit containing a combination of capacitors and a single inductor.

• In circuits containing only a charged capacitor and an inductor (LC circuits), the maximum current in the inductor can be determined using conservation of energy within the circuit.
• In LC circuits, the time dependence of the charge stored in the capacitor can be modeled as simple harmonic motion. Derived equation: dq2 1 qdt2 =− LC
• The angular frequency of an oscillating LC circuit can be derived from the differential equation that describes an LC circuit. Derived equation: TOPIC 13.6 Circuits with Capacitors and Inductors (LC Circuits)
