The rms value of potential difference V shown in the figure is

Options

  1. AV₀
  2. BV₀ 2
  3. CV₀ 2
  4. DV₀ 3

Correct answer

B. V₀ 2

Step-by-step solution

V_ rms = [ 1 T ₀^ T / 2 V₀^2 d t ]^ 1 / 2 aligned & = [ V₀^2 T [t]₀^ T / 2 ]^ 1 / 2 & = [ V₀^2 T ( T 2 ) ]^ 1 / 2 V_ rms & = [ V₀^2 2 ]^ 1 / 2 V_ mms & = V₀ 2 aligned
