Question

What is the peak value of 220 V a.c.?​

Answer 1

Answer:

Peak value of 220V a.c. is root(2)*220 = 1.414*220V. This is because 220V is the r.m.s. value and not the peak value. An AC voltmeter reads a sine wave to be 2 volt.

Answer 2

The peak value of the AC source is 311.12 volts.

Explanation:

Given that,

The rms vale of voltage is, $V_{rms}=220\ V$

We need to find the peak value. We know that the rms value of AC source is given by :

$V_{rms}=\dfrac{1}{\sqrt{2} }\times V_p$

$V_p=\sqrt{2} \times V_{rms}\\\\V_p=\sqrt{2} \times 220\\\\V_p=311.12\ V$

So, the peak value of the AC source is 311.12 volts.
