A house has 3 tube-lights of 20 watts each. On the all the tube-light are kept on for five hours. Find the energy consumed in 30 days.

Text Solution

Verified by Experts

Number of tube light = 3
Wattage = 20 watts each
Consumed hours = 5 hrs
Energy = `=(3xx20xx5)/(1000)=(300)/(1000)KWH=0.3KWH`
Consumed energy for 30 days `=0.3xx30=9KWH(or) 9" units "`
