How To Calculate Your Electricity Bill
A consumer consumes 1000 watts load per hour daily for one month.Calculate The Total Energy bill of the consumer if per unit rate is 9 (In INR ,Rs, $, DHR, or Riyal etc) [Take 1 month = 30 Days]Solution
1unit = 1kWh.
So Total kWh = 1000 x 24 x 30 = 720000 watts/hour
we Want to convert it into Units, Where is 1unit = 1kWh.
So total Consumed units. 720000/1000…… (k=kilo=1000)
Total Units = 720.
Cost of per unit is 9.
So total Cost or bill= 720 x 9 = 6480. (In INR,Rs, $, DHR, or Riyal etc)
[Also note that…why we multiply with 24 although the daily rate is given.. It is not Daily Rates...It’s the rate Per Unit...Where 1 unit = 1 kWh (Also Called 1 =B.T.U = Board of Trade Unit)... It means...If you switched on a 1000 watt bulb for 1 hour...It mean you consumed 1000 watts for an hour... (1000 watts for 1 hour = 1kWh = 1 unit of Energy) So if the rate of unit is 5 Dollars, then you will pay 5 Dollars as a bill for your bulb]
