Calculate the instantaneous voltage for AC supply of 220 V and 50 Hz.

Text Solution

Verified by Experts

Given : `E_(v)=220V`
`gamma=50Hz`
E = ?
To find :
We can use `E_(v)=(E_(m))/(sqrt(2))`
`E_(m)=sqrt(2)xxE_(v)`
`=sqrt(2)xx220`
= 311.08 V.
`therefore" Instantaneous Voltage "E=E_(m)sinomegat`
`E=E_(m)sin(2pigamma)t`
`=311sin(2pixx50)t`
`=311sin100pit.`
