Device. It seems obvious, but that consume electricity identified is necessary for the correct calculation. Know the power of each electrical device. This can be seen on the device itself (some have a plate) or in the manual. They are measured in watts (w). The time that each device is working. If it is connected all day or for a period of time, if it is turned on once a week or every day, if the use is seasonal, … these three factors to take into account are the basis for calculating the electrical power that i am going to consume. It is important to consider, as the consumption
is in kwh (kilowatts/hour), that the power of the device must be multiplied by the time of daily use that is given to it. Subsequently, the weekly, monthly e commerce photo editing or annual calculation will be obtained. For example, a hair dryer with a power of 1600 watts, with a daily use of 5 minutes, consumes: 1600 w x 5 minutes/day = 0.133 kwh each day 0.9 kwh each week 4 kwh each month 48.6 kwh each year it is convenient to bear in mind that the energy consumption of the device will depend exclusively on its power and the time it is connected. If i do the calculation, will it match my electricity bill?
It may be yes, it may be no. The answer to this question will depend on how precise the calculation was. But, almost with a 100% probability, you are not going to hit. Although you can make an estimate very close to reality . The problem, generally, will come from those electrical devices that do not have a fixed use. In other words, we can obtain, in a very approximate way, the consumption of the refrigerator, a hair dryer that i use every day, the toaster, the phone charger or even the heating; but it is difficult to know the consumption of a television
