MCQ
The peak voltage in a $220V\ AC$ source is:
- A$220V.$
- BAbout $160V.$
- ✓About $310V.$
- D$440V.$
✓
Answer
Correct option: C.
About $310V.$
$\text{V}_\text{rms}=220\text{V}$
$\text{V}_\text{p}=\sqrt{2}\times\text{V}_\text{rms}$
$=220\times1.414=311\text{volt}$
$\text{V}_\text{p}=\sqrt{2}\times\text{V}_\text{rms}$
$=220\times1.414=311\text{volt}$
