peak value = r.m.s value * root2

Ramrajya said:   1 decade ago
That means peak value is equivalent to average value.

RMS value = avg.value/root2.

Vrms = 230 V.

Vp = Vrms*1.414.

= 230*1.414 = 325.22.

Hence option C.

How 1.414?

Sai Prahjval said:   7 years ago
Peak value is 1.414 times the RMS voltage. On a 240 volt circuit the peak voltage is 240 x 1.414 = 339.36 volts.

The peak to peak value is twice this.

How come 1.414? Please explain.

@Tushar.

√2=1.414.

We know that Vp = Vrms/0.707.

We get Vp = 230/0.707 = 324.31.
