In a L C R oscillatory circuit, find the energy stored in inductor at resonance if voltage of source is 10 ~V , resistance is 10 and inductance =1 H .

Options

  1. A0.5 ~J
  2. B2 ~J
  3. C4 ~J
  4. D10 ~J

Correct answer

A. 0.5 ~J

Step-by-step solution

At resonance, current I= V Z_ = V R = 10 10 =1 ~A Energy of inductor = 1 2 L I^2= 1 2 (1)(1)^2=0.5 ~J
