What is the value of DC equivalent output voltage for the given circuit, given that the input voltage is 20 Vp-p and 50 Hz and the diode is a silicon diode?(a) 2.9574 V(b) -2.9574 V(c) -3.125 V(d) 0 VThe question was posed to me in quiz.My doubt stems from Diode Gates and Rectifiers topic in division Diode Circuit of Analog Circuits

Answer»

Correct answer is (b) -2.9574 V

For explanation: Vdc is GIVEN by 0.318(Vp). Here Vp = 10-0.7 V = 9.3 V and hence, Vdc = 0.318 x 9.3 V = 2.9574 V. Now, as the OUTPUT Is NON zero only for the negative half cycles of the input, Vdc = -2.9574 V.
