The main meter of a house is marked 10 A-220V. How many 60 W electric lamps can used safely in this line ?

Text Solution

Verified by Experts

Maximun power of the household line ,
`P=VI=220xx10=2200W`
`therefore` Maximun number of 60 W lamp = `(2200)/(60)=36.67`
So , maximum 36 lamps canbe used at a time .
