For the circuit shown below, instantaneous current through inductor ' L ' and capacitor ' C ' is respectively.

Options

  1. A- e ₀ L t ; e ₀ c t
  2. B- e ₀ L t ; e ₀ C t
  3. Ce ₀ C L t ; e ₀ ~L C t
  4. D- e ₀ C L t ; e ₀ ~L C t

Correct answer

A. - e ₀ L t ; e ₀ c t

Step-by-step solution

The current through the inductor lags the applied emf by 2 and the current through the capacitor leads the current by 2 aligned & i _ L = e ₀ L ( t - 2 )=- e ₀ L t & and i _ c = e ₀ C ( t + 2 )= e ₀ C t aligned
