In the given circuit, r m s value of current I r m s through the resistor R is :

Options

  1. A2   A
  2. B1 2   A
  3. C20   A
  4. D2 2   A

Correct answer

A. 2   A

Step-by-step solution

Impedance of the given LCR circuit will be, Z = R 2 + X L - X C 2 ⇒ Z = 100 2 + 200 - 100 2 = 100 2 Ω Therefore, RMS current can be written as, I r m s = V r m s Z = 200 2 100 2 = 2   A
