Electrostatic Potential And Capacitance

Question

The peak voltage of an ac supply is 300 V. What is the rms voltage?

Solution

Given,

$Peak volatge, E_{0} = 300 V Rms value of current, I_{rms} = 10 A$

Now,
Using the relation,

$E_{rms} = \frac{E_{0}}{\sqrt{2}}$

$= \frac{300}{\sqrt{2}} = \frac{300}{1.414} = 212.13 V$
