Question

An electric kettle rated at 2.2 kW works for 4 hours a day. Calculate the number of units consumed by it in 20 days .​

Answer 1

Answer:

Given,

Power = 2.2 kW

= 2200 W

Time = 4 hours

Units consumed in a day = Wattage*Hours/1000

= [2200*4]/1000

= 8.8 kWh

Units consumed in 20 days = 8.8*20 kWh

= 176 kWh

I hope this helps.
