A single phase half wave rectifier is feeding a resistive load. When a = 0, dc output voltage is 127 V. When a = 30°, the dc output voltage will be about

[A].	127 V
[B].	120 V
[C].	110 V
[D].	100 V

Answer: Option B

Explanation:

Using Eq 286-233-2

286-233-1

Hence V_dc for 30° firing angle = 0.933 x 127 = ≈ 120 V.
