Energy consumption is the use of power or energy of a system by making use of supply. The consumption is done in Giga Joule per year, kilograms of oil equivalent per year (kg/a), and in Watts.
Formula of Energy Consumption
The energy consumption formula is articulated as,
Where,
- E is energy in kilowatt-hours(kWh),
- P is power in Watts,
- t is hours
Energy Consumption Solved Problems
Here are some cracked examples based on Energy Consumption:
Problem 1:Â Compute the energy consumption in a system that consumes 190 Watts of power and works for 3 hrs a day.
Answer:
Given: Power P = 190 W, total number of hours = 3 hrs
E =(190*3*60*60)/1000
E =2052 kWh
Therefore, the energy consumption is 2052Â kWh
Problem 2:Â A toy car consumes energy of 500 Watts of power if it works for 2 hrs a day using it. Calculate the energy consumption a day.
Answer:
Given: Power P = 500 W, total number of hours= 2 hrs
E = (500*2*60*60)/1000
E =3600Â kWh
