A house has 3 tube lights of 20 watts each, On the average, all the tube lights are kept on for five hours. Find the energy consumed in 130 days.

Text Solution

Verified by Experts

Number of tube lights =3
Wattge = 20 watts each
Consumed hours = 5 hrs
Energy `= (3 xx 20 xx5)/(1000)`
`= (300)/(1000)` KWH
= 0.3 KWH
Consumed energy for 30 days
`= 0.3 xx 30 = 9` KWH (or) 9 units.
