The r.m.s. value of potential difference V shown in the figure is

The r.m.s. value of potential difference V\mathrm{V} shown in the figure is The r.m.s. value of potential difference V shown in the figure is

Options

  1. AV0\mathrm{V}_{0}
  2. BV0/2\mathrm{V}_{0} / \sqrt{2}
  3. CV0/2\mathrm{V}_{0} / 2
  4. DV0/3\mathrm{V}_{0} / \sqrt{3}

Correct answer

B. V0/2\mathrm{V}_{0} / \sqrt{2}

Step-by-step solution

Vrms=(T/2)V02+0T=V02\mathrm{V}_{\mathrm{rms}}=\sqrt{\frac{(\mathrm{T} / 2) \mathrm{V}_{0}{ }^{2}+0}{\mathrm{ T}}}=\frac{\mathrm{V}_{0}}{\sqrt{2}}.
