LC Oscillation FrequencyMediumQuestion 20201

Question

A charged capacitor is connected to an inductor. Frequency of oscillation is:
  1. A
    2π/√LC
  2. B
    1/(2π√LC)
    Correct
  3. C
    √LC
  4. D
    2π√LC

Correct answer

1/(2π√LC)

Explanation

LC circuit oscillates at f = 1/(2π√LC). The capacitor's electric energy and the inductor's magnetic energy exchange sinusoidally with no dissipation in the ideal case.
