Have you ever thought about how much electricity the light bulb consumes in your house? Or how much power does the television or any other electric appliance in your house consume? The increasing electric bill has always remained a debatable thing in nearly everyone’s house. And most of the time, people blame heavy appliances like refrigerators, air conditioning, etc. for the increased bill amount. But that’s not the fact.
Through this piece of information, we shall learn how to calculate the power consumption of every electric appliance available in your home.
Things needed to calculate power consumption:
For calculating the power consumption of any appliance, the very first thing needed is the appliance and the technical specification that is given along with the appliance. This is available on the electric appliance in the form of a sticker. If for any reason the sticker isn’t available on the electronic device, you can simply look for the sticker or technical specification details on the internet through the website of the appliance manufacturer or any online shopping website.
Calculating the power consumption of any appliance
Before initiating the calculation of the power consumption, there are certain terms and conditions you need to know.
Wattage is nothing but the power rating of the appliance. Wattage helps with an approximate rate or indicator at which the appliance consumes power. For example, if behind your television 50 watts is mentioned, it means the electric consumption of your television would be 50 watts/hour.
Operational hours indicate the total number of hours any device is operated. Suppose, if you are willing to measure the power consumed by your television for 5 hours, the operational hours while calculating the power consumption is 5 hours.
Also termed kWh, Kilowatt-hours is nothing but the power unit. This is the value you are willing to calculate the electricity provider charges for every kilowatt-hour of electricity the house consumes.
Now that all the terms are clear in your mind, here is how you can calculate the power consumption.
How to calculate the power consumption of an appliance?
To your surprise, there is a simple power consumption formula that can be used for calculating power consumption.
The formula is very simple:
Power consumption of an appliance = Wattage x Operational hours
However, the values of the formula change as per your calculation consumption. That is whether you are going for daily energy consumption, monthly energy consumption, or annual or yearly energy consumption. So, here are the formulas for the same.
For Daily energy consumption, the formula is:
Daily power consumption = Wattage ratting x number of hours
For monthly energy consumption, the formula is:
Monthly power consumption = Wattage ratting x number of hours x number of days
For annual or yearly energy consumption the formula is:
Annual power consumption = Wattage ratting x number of hours x 365 days
Let’s take a simple example for understanding how the formula works for calculating the appliance power consumption.
Suppose the power is consumed by a LED TV of 100 Watt that runs for 24 hours every day for a month. So, what would be the power consumption of the LED TV?
Following the formula for daily consumption, the wattage in this example is 100 Watt. And the operational hours are 24 x 30 days, which is 720 hours every month.
Hence, the power consumed by the 100 watts LED TV would be:
Power consumed by LED TV = 100 watts x 24 hours
Hence, the power consumed by the LED TV is 2400 watts hours for daily calculation.
Similarly, for monthly power consumption, the calculation would be:
Monthly Power Consumption = 100 watts x 24 hours x 30 days
Hence, the power consumed by the LED TV is 72000 watts hours for monthly consumption.
Similarly, for yearly power consumption, the calculation would be:
Annual Power Consumption = 100 watts x 24 hours x 365 days
Hence, the power consumption by the LED TV is 876000 hours for yearly consumption.
However, it should be kept in mind that if you are calculating the power consumption of any electronic appliance that comes with a compressor, the calculated value of the appliance would be quite high compared to the actual value.
How to calculate the electricity bill?
Now that you already know how to calculate the power consumption of the electronic appliance, the next step is to calculate the electricity bills. For this, you need to have your last month’s light bill handy to know how much you have paid per kWh or else, know the electric rate.
Here is the formula to find the electric bill amount.
Monthly Usage (kWh) x Electric Rate ($/kWh) = Appropriate cost per month
However, it should be kept in mind that the appliances hold only a particular portion of your entire electricity bill. This is because there are other appliances on the list like cooling, heater, lighting, etc.
As there are various electronic appliances in a house, there are several exceptions that also affect the calculation. The primary exception is the compressor of the electronic appliance. Electronic appliances like AC, refrigerators, etc. carry compressors inside them. The compressors do not work or say are not ON every time. Again, they might not also work at the same speed every time. Hence, the consumption of power is not the same every time. It keeps on varying depending on the load the appliance is taking.
Henceforth, while using the electronic unit calculator for calculating such electronic appliances, the actual consumption can either be higher or lower than the calculated consumption. Luckily, such appliances come with a sticker that reveals the annual power consumption of the appliance along with the power saving guide that helps in learning about the appliance with ease.
