Question

the peak value of the input to a half - wave rectifier is 108. the approximate peak value of the output is v

Explanation:

Step1: Consider diode voltage drop

In a half - wave rectifier, assume a silicon diode with a voltage drop \(V_D = 0.7\ V\)

Step2: Calculate output peak voltage

The input peak voltage \(V_{in(peak)}=108\ V\). The output peak voltage \(V_{out(peak)}=V_{in(peak)}-V_D\)
Substitute the values: \(V_{out(peak)} = 108 - 0.7=107.3\approx107\ V\)

Answer:

107
