An alternating voltage e = 200 2 sin ⁡ 100 t volt is connected to 1 μ F capacitor through AC ammeter. The reading of ammeter is

Options

  1. A5 mA
  2. B10 mA
  3. C15 mA
  4. D20 mA

Correct answer

D. 20 mA

Step-by-step solution

e = e 0 sin ω t e 0 = 200 2 V I r m s = υ r m s X C = e 0 ω C 2 = 200 2 × 100 × 10 − 6 2 = 2 × 10 − 2 = 20 m A
