A 40   μF capacitor is connected to a 200   V , 50   Hz AC supply. The rms value of the current in the circuit is, nearly:

Options

  1. A2.05   A
  2. B2.5   A
  3. C25.1   A
  4. D1.7   A

Correct answer

B. 2.5   A

Step-by-step solution

Current flowing through the capacitor is given by, I rms = V X C = V 1 / C ω = V C ω ⇒ I rms = 200 × 40 × 10 − 6 × 2 π × 50 ⇒ I rms = 2.5   A
