Q10 / 117 · NTA Abhyas (NEET) 2020 · Physics · Alternating Current

The maximum voltage in DC circuit is $282 V$ . The effective voltage in AC circuit will be

Correct answer
A
$200 V$
B
$300 V$
C
$400 V$
D
$564 V$

Solution

Maximum voltage is AC circuit

V_{0} = 282 V

V = \frac{V_{0}}{\sqrt{2}} = \frac{282}{\sqrt{2}}

V = \frac{282}{1.41} = \frac{28200}{141}

V = 200 V

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