LC Circuit — Current MaximumMediumQuestion 20224

Question

In an LC oscillation, current in the circuit is maximum when:
  1. A
    Capacitor is fully charged
  2. B
    Capacitor is fully discharged
    Correct
  3. C
    Inductor has zero energy
  4. D
    Frequency equals zero

Correct answer

Capacitor is fully discharged

Explanation

When the capacitor is fully discharged, all the energy is in the inductor (maximum current). When fully charged, current is zero and all energy is in the capacitor (electric field).
