In the circuit shown here, the point ' C ' is kept connected to point A '' till the current flowing through the circuit becomes constant. Afterward, suddenly, point ' C ' is disconnected from point A '' and connected to point ' B ' at time t = 0 . Ratio of the voltage across resistance and the inductor at t = L R will be equal to :

Options

  1. Ae 1 - e
  2. B1
  3. C- 1
  4. D1 - e e

Correct answer

C. - 1

Step-by-step solution

Applying Kirchhoff's law in closed loop, - V R - V L = 0 ⇒   V R     V L   = -   1
