In an AC circuit, the current is I = 100 (5t) A. The value of I_ rms is

Options

  1. Azero A
  2. B50 2 A
  3. C25 A
  4. D25 2 A

Correct answer

B. 50 2 A

Step-by-step solution

The given alternating current is I = 100 (5t) A. The peak value of the current is I₀ = 100 A. The root mean square (rms) value of the current is given by I_ rms = I₀ 2 . Substituting the value of I₀ : I_ rms = 100 2 = 50 2 A. Answer: 50 2 A
