A 100   Ω resistance and a capacitor of 100   Ω reactance are connected in series across a 220 V source. When the capacitor is 50 % charged, the peak value of the displacement current is

Options

  1. A2.2 A
  2. B11     A
  3. C4.4     A
  4. D11 2 A

Correct answer

A. 2.2 A

Step-by-step solution

Given, R = 100   Ω , X C = 100  Ω . Z = X C 2 + R 2 = 100 2   Ω . V max = 220 2   V . I max = V max Z = 220 2 100 2 = 2.2   A .
