The diode \mathrm{D} will conduct for positive half cycle of \mathrm{a. c.} supply because this is forward biased. For negative half cycle of \mathrm{a. c.} supply, this is reverse biased and does not conduct. So out put would be half wave rectified and for half wave rectified out put
\mathrm{V_{r m s}=\frac{V_0}{2}=\frac{200 \sqrt{2}}{2}=\frac{200}{\sqrt{2}}}
