Energy Consumption Formula
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.
The energy consumption formula is articulated as,
E is energy in kilowatt-hours(kWh),
P is power in Watts,
t is hours per day.
Energy Consumption Solved Problems
Here are some cracked examples based on Energy Consumption:
Problem 1: Compute the energy consumption in a system that consumes 190 Watts of power and works for 3 hrs a day.
Given: Power P = 190 W, th/day = 3 hrs
Therefore, the energy consumption is 2052J
Problem 2: 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.
Given: Power P = 500 W, th/day = 2 hrs
