LC Oscillations Quiz Practice Quiz | AC Circuits

Q: What fundamental principle governs the energy storage in a capacitor?

Electric field — Capacitors store energy in the form of an electric field.

Q: In an LC circuit, what component stores energy in a magnetic field?

Inductor — The inductor stores energy in a magnetic field when current flows through its coil.

Q: What happens to the electric field when a charged capacitor is discharging in an LC circuit?

It collapses and energy is transferred to the inductor. — The electric field collapses as the capacitor discharges, transferring energy to the inductor.

Q: Which of the following describes the key characteristic of an LC oscillation?

Continuous exchange of energy between electric and magnetic fields — LC oscillations involve the continuous exchange of energy between the capacitor and the inductor.

Q: For AC applications, what type of capacitor should be used?

Non-polarized capacitor — Non-polarized capacitors are necessary for AC applications to prevent damage or malfunction.
