Q16 / 117 · NTA Abhyas (NEET) 2020 · Physics · Alternating Current

The peak voltage in a $220 V$ AC source is

A
$220 V$
B
about $160 V$
Correct answer
C
about $310 V$
D
$440 V$

Solution

Given root mean square voltage,

V_{r m s} = 220 V

Peak voltage will be given by,

V_{p e a k} = \sqrt{2} V_{r m s}

V_{p e a k} = \sqrt{2} (220)

V_{p e a k} \approx 310 V

Hence, the correct answer is option: 'C'.
