What is used to determine the amount of electrical energy being consumed?
The standard measure of electricity consumption is the amount of watts expended over the period of one hour, which is also known as a watt-hour. This means if a 40 watt light bulb is turned on for one hour, it will use 40 watt-hours of electricity.
How do you calculate the energy consumption of an electrical appliance?
To calculate power consumption of any appliance, you have to multiply it’s wattage by the number of hours it is being used (operational hours). For example, a 1000 watt electric iron running for one hour will consume (1000 watt X 1 hour) 1000 watt hour or 1 kilowatt hour (kWh) of electricity.
What is the total energy consumed in a day?
In 2019, the world primary energy consumption was 13.9 billion toe (ton of oil equivalent). With a world population of about 7.7 billion, we now have a world average consumption of primary energy of 58 kWh per day per person.

What is the difference between power and current?
Power is the product of voltage and current and is the work done in moving a quantity of charge through a resistance.
What is the relationship between current and power?
The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every t seconds passing through an electric potential (voltage) difference of V is P=QVt=IV P = QV t = IV , where Q is electric charge in coulombs, t is time in seconds, I is electric current in amperes, and V is electric …
