Question

The peak voltage in a $220\text{V}$ alternating current is

• A. $220\text{V}$
• B. About $160\text{V}$
• C. About $310\text{V}$
• D. $440\text{V}$

Answer 1

The correct option is C About $310\text{V}$

Given:
$V_{rms}=220\text{V}$

As we know that
$V_0=\sqrt{2}{V}_{rms}$

Therefore
$V_0=\sqrt{2}\times 220=311.08$ volt
