Tha Manga Giude to Electricity - 5 Appliances

The Manga Guide to Electricity

Calculate how much it costs to use five common appliances that you use every day in your home for 24 hours. Please let me know the appliance, its wattage, amps and volts of each appliance and how you calculated cost. You will need to go to GRU or look at one of your electric bills.

1.Alienware m14x laptop

19.5v(7.7A)=150.15W 

150.15W(24HRs) = 3603.6Ws per 24Hrs 

3603.6/1000 = 3.6035kWH 

3.6035kWH($.031)= $0.111 per Day of usage

2.Fridge

1200 Watts
1200W(24HRs) = 28,800Ws per 24Hrs

28,800/ 1000 = 28.8kWH

28.8kWh($.031)= $.8928  per Day of usage

3. TV

120 Watts 

120W(24HRs) = 2880

2880/1000= 2.88kWh 

2.88kWh($.031) = $0.089  per Day of usage

4. Air Conditioning 

3500 Watts 

3500W(24HRs) = 84,000W

84,000/ 1000 = 84kWh

84kWh($.031) = $2,6  per Day of usage 

5. Fan

120 Watts 

120W(24HRs) = 2880

2880/1000= 2.88kWh 

2.88kWh($.031) = $0.089  per Day of usage
