WATTMETER

The wattmeter is the device that allows the measurement of the watts in a current of electricity. Watt, also known as watt , is the unit of measurement that equals one joule per second and is used to measure power .

Wattmeter

We must be aware that there are fundamentally two types of wattmeters: analog wattmeter and digital wattmeter.

Wattmeters are made up of a moving coil (the voltmeter coil ) and two stationary coils (the amperometric coils ). The voltmeter coil is connected to the electrical circuit in parallel, while the amperometric coils have a series connection .

When electric current circulates through the amperometric coils, an electromagnetic field is produced that has a power proportional to the current. The voltmeter coil, for its part, has a resistance that allows minimizing the current flowing through it. Through a needle located in the voltmeter coil, the wattmeter indicates the power of the circuit.

It is important to note that overloading can damage the wattmeter coils, causing measurements to become inaccurate. According to the current , the voltage and the power factor, the superheat will be lower or higher.

Other data that is worth knowing about the aforementioned device are these:
-The amperometric coil or ammeter, what it does directly is to measure the intensity of the electric current. The unit of measurement that it uses is the ampere and then also other "submeasures" such as the milliamp or even the microampere. It has a parallel resistance that responds to the name of shunt.
- Being able to know the origin of the unexpected rise or fall of a device is one of the main functions of the aforementioned ammeter, which is also used to repair current surges that are causing the malfunction of a system in question.
-The voltmeter coil is also known as a voltmeter and its mission is to measure the value of the voltage. Volt (V) is used as the main unit of measurement, but other “measurements” can also be used. These include the kilovolt (KV), the micro volt, or the millivoth (mV), for example.
-The frequency range of what is an electronic wattmeter can reach up to 20 megahertz. Of course, to achieve this you have to make use of what are called pentode tubes, which would replace the more "traditional" triodes.
-Currently the wattmeter is very frequently used by professionals who carry out connections to the Wifi network.

It is known as an electronic wattmeter , on the other hand, the instrument that can carry out energy storage to sustain a field of electricity. It has conductive plates separated from each other by vacuum or by a dielectric type material. When placed before a potential difference, the electronic wattmeter plates acquire negative and positive electrical charges (depending on the plate), although the changes in the total charge are null.

TOURIST AREA

 A section of a surface or a piece of land is called a zone . Tourist , on the other hand, is an adjective that refers to what is linked to tourism (the activity carried out by a person when they travel to a place other than their residence and spend the night in that place). A tourist area , in this way, is a space that, due to its attractions , attracts a large number of visitors . An area can become touristy due to its natural beauty , its leisure infrastructure, its historical buildings or its offer of events, to name a few possibilities. It is possible to differentiate between a residential area and a tourist area. While in the former private homes predominate, in the tourist area there are usually hotels , restaurants and other establishments for leisure and rest. You can also distinguish between a tourist area and an industrial area , where factories abound. In a large city , it is common for tourist areas, residential areas and industrial areas to coexist. In a locality X , it

QUANTITATIVE VARIABLE

Image
The symbol that appears in propositions, algorithms, formulas and functions and that takes different values ​​is called a variable . According to their characteristics, it is possible to distinguish between different classes of variables. The quantitative variables are those that adopt numerical values (ie, numbers). In this way they differ from qualitative variables , which express qualities, attributes, categories or characteristics. It is important at this point that we proceed to know the etymological origin of the two words that give shape to the term that concerns us: -Variable comes from Latin, specifically derived from "variabilis", which can be translated as "that can change its appearance" . It is the result of the sum of two components: the verb "variare", which is synonymous with "change of appearance", and the suffix "-able", which is used to indicate possibility. -Quantitative, for its part, comes from Latin as we

Down

Abajo is an adverb that is very frequently used in our language. The term can refer to that or that which is located in a lower place with respect to another thing or individual. For example: " The pink shirt is stored in the bottom drawer, not that one " , " My grandmother lives downstairs: I'm on the fifth floor and she is on the fourth " , " I'm going to put the boxes underneath out of bed ” . The notion below also refers to what advances or goes to a lower sector , or what ranks lowest in comparison with something that lies higher up: " The owner of the cottage intends to take the tree down, but Neighbors are opposed ” , “ Due to the overturn, the driver was left with his head down ” , “ We will have to walk an hour downhill to get to the shelter ” . In certain texts , the mention below allows to allude to something that will appear next and that will be noticed once the reading progresses. A statement can begin by saying " The und
