# In half wave rectifier if the D.C component at output is $\large\frac{10}{\pi} $$V What is the peak value of sinusoidal input signal. (a)\;\frac{10}{\sqrt 2} V \\ (b)\;10 \;V \\ (c)\;\frac{20}{\pi} V \\ (d)\;10 \sqrt 2 \;V Can you answer this question? ## 1 Answer 0 votes If V_{peak} is the peak value of the input sinusoidal wave for half wave rectifier the average value of output or DC value = \large\frac{V_{Peak}}{\pi} \therefore V_{DC}=\large\frac{V_{peak}}{\pi} V_{DC}=\large\frac{10}{\pi}\;$$volts$
$\therefore V_{peak}=\large\frac{10}{\pi} \times \pi$
$\qquad= 10\;volts$
Hence b is the correct answer.
