MCQ
The peak voltage in a 220V AC source is:
- A220V.
- BAbout 160V.
- ✓About 310V.
- D440V.
✓
Answer
Correct option: C.
About 310V.
$\text{V}_\text{rms}=220\text{V}$
$\text{V}_\text{p}=\sqrt{2}\times\text{V}_\text{rms}$
$=220\times1.414=311\text{volt}$
$\text{V}_\text{p}=\sqrt{2}\times\text{V}_\text{rms}$
$=220\times1.414=311\text{volt}$
