What is the dc component of the output voltage if a sinusoidal signal of 33 V peak voltage is the input of a half wave diode rectifier circuit?
Options
- A3.5 V
- B12.5 V
- C10.5 V
- D2.9 V
Correct answer
C. 10.5 V
Step-by-step solution
For a half-wave rectifier, the output voltage is a rectified sine wave. The dc component or the average value of the output voltage V_ dc is given by the formula V_ dc = V_m , where V_m is the peak voltage of the input sinusoidal signal. Given V_m = 33 V, we substitute this value into the formula: V_ dc = 33 Using the approximation 3.14159 : V_ dc 33 3.14159 10.504 V. Rounding to the nearest value provided in the options, we get 10.5 V. Answer: 10.5 V
