the peak velue of AC voltage on a 220V mains is root 2 times of root mean square velue

Assertion : An electric bulb is first connected to a dc source and then to a ac source having the same brightness in both the cases. Reason : The peak value of voltage for an A.C. source is sqrt(2) times the root mean square voltage.

Root Mean Square Velocity

The peak voltage in a 220 V AC source is

The peak value of alternating voltage is 423 V. its root mean square value is

When an AC voltage of 220 V is applied to the capacitor C

When an A.C voltage of 220 V is applied to the capacitor C

Calculate the peak value of voltage and mean value of voltage during a positive half cycle in an AC circuit with root mean square value of voltage 50sqrt(2) V.
