Question
The output of the diode circuit shown in the figure is connected to an averaging DC voltmeter. The reading on the DC voltmeter in Volts, neglecting the voltage drop across the diode, is __________.

Correct answer
3.15 to 3.21
Solution
1.The circuit shown is a basic half-wave rectifier.
2.The input voltage is . The peak voltage is .
3.Neglecting the diode voltage drop, the output voltage follows the input during the positive half-cycle and is zero during the negative half-cycle:
- for
- for
5.Substituting :
