We look at the passport
The first way is to look into the device passport. All factory units are supplied with a sticker on the box, instructions and a passport with a warranty. These books indicate the range, operating conditions and technical data.
Above is a small fragment of passport data, or rather, a table containing data from the model range of convector heaters. Column 1 indicates the current passing through the device, and the second column indicates how much electricity the device consumes when TEN one and two are turned on. Here is an example of a heater using a passport, you can easily find out the power consumption of the device. Likewise, you can limit the consumption of a TV or even an LED lamp.
Ohm’s law to the rescue!
The second method is to determine the current strength and calculate the consumption using the formula, Ohm’s law. We take a multimeter, turn on the contact or resistance measurement mode. We measure the resistance R ten. Now we can calculate the current that can pass through the system A ten. To solve the formula, you need to know the voltage, but it is 220 V in the home network.
After finding the current, you can determine the power of the device. For this, we multiply the amps by volts.
We use an electric meter
Method 3 – Almost all meters are equipped with an indicator light, the number of flashes means some power consumption / kW.
We turn off all consumers in the apartment, leaving only the device in question connected. Within 15 minutes, we count the pulses and multiply them by four (to get the amount per hour). After knowing the number, divide it by imp/kW and find out the unit power.
You can also record the meter reading and turn on the device we are trying to select for some time, preferably an hour. We record new readings, take old ones from them, and as a result we find out the approximate power.
The electronic meter allows you to view all parameters in real time: current, power consumption, network voltage, by sorting through the meter menu.
An analogue of an electric meter can be a household wattmeter, with which you can quickly and accurately determine the power consumption of electricity by the device. The video below demonstrates the operation of this device:
Current clamp meter
If there are current clamps, it is easy to determine the consumption. To do this, it is necessary to measure the current in one of the conductors connected to the device.
If there are no current clamps at hand, it is better to use a conventional tester. Every electric meter, even self-taught, should have this meter in their arsenal.
So we looked at how to determine the power consumption of the device by current, formula and meter readings. We hope that the presented methods were interesting for you and were useful in independent determination of parameters!

Jezli website for purchasing electrical appliances
When we say Jeezly website, we are talking about one of the most famous Arab websites that was able, in a very short period of time, to achieve a very large demand for purchases from it by people from various parts and sectors of the Arab world.
On the Jeezly website, you will find a joint look and all the products that you may need in your home, starting with those for kitchens or bathrooms, but even those for gardens, you will find them on this wonderful site.
So, if you were lost before and did not know where to go to buy your products on the Internet, now you have the perfect solution, and all you have to do is go to the Jezli website and start choosing the products you want.
What are the features of Jeezly ?
Since we are talking about a site that is preferred by many people around the world, there is no doubt that it is a site full of various features and characteristics. Therefore, we have decided to devote our next paragraph to pointing out the most prominent features of the Jezli site.
One of the most prominent features of the site is the proportionality of prices. On the Jeezly website, you do not have to worry about the imaginary prices of the products, as is the case with most sites that display their products on the Internet.
The price of delivering products is very reasonable and not expensive, and the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.
One of the features of the site is also the high quality of its products, as it is impossible to find a poor quality product. Rather, the Jezli website deals with the major companies, Philips, for example, and other famous brands, so you must remove from your mind the idea of the poor quality of one of the products. Another advantage of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments, and many other types.
Jeezly website also accepts what is known as the shopping cart, which makes it easy for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.
Accepts multiple payment methods.
