MCQ
The value of form factor in case of half wave rectifier is
- A$1.11$
- ✓$1.57$
- C$1.27$
- D$0.48$
✓
Answer
Correct option: B.
$1.57$
b
(b)
(b)
Form factor $=\frac{\text { rms of out put voltage }}{\text { average value of out put voltage }}$
or form factor $=\frac{v_{\max } / 2}{v_{\max } / \pi}=\frac{\pi}{2}=1.57$
