shakunthala posted this q…that

Whatt-hour is a itegrated or obsolute

ans} watt-hour meter is also called as energy meter … it can read the energe and also record it for

feture use …because of this reasion it can be called as itegrated meter . e.g our house service meter

.as for as i know i posted this ans ..if it is wrong then mail me to ganesh.gomavarapu@gmail.com
