WATT

Watt is a unit of measurement that is part of the International System . The term, synonymous with the English word watt , is used in power measurements and is equivalent to one joule per second .

Watt

The watt, which has the W as its symbol , pays homage to the British mathematician and engineer James Watt , who was born in 1736 and died in 1819 . Watt was one of the great people in charge of the development of the steam engine.

One of the areas of use of the watt as a unit of measurement is the field of electricity . The electrical power of a device can be expressed in watts and, if it is very powerful, in one of its multiples (such as kilowatts or megawatts ).

The idea of electrical power refers to the rate of generation or use of energy when carrying out work. If we have an 80-watt light bulb on for sixty minutes , we will have consumed 80 watt-hours . It should be noted that the watt-hour reflects power over time (the amount of energy generated to maintain a certain power for a certain time). We said lines above that a watt is equal to one joule per second: that device that consumes one watt of electrical power will be consuming one joule per second. If the bulb draws 80 watts for one hour , therefore it will consume288,000 joules in that period.

80 watts in an hour = 80 joules per second x 3600 (in each hour there are sixty minutes; in each minute, sixty seconds. Therefore: 60 x 60 = 3600)

80 watt-hours = 288,000 joules

The power of machinery, motors and power plants is usually expressed in watts or kilowatts. These units, in turn, have equivalents in horsepower and horsepower , to name two possibilities.

In addition to all the above, we have to emphasize that, on numerous occasions and by people of very different kinds, confusion is created regarding the watt. Specifically, what we are referring to is that they are capable of confusing it with the volt (V), since both terms are used within the electronic and electrical field.

To avoid falling into this error, and starting from the explanation we have given about the watt, we must know that the volt refers to the voltage or the potential voltage. That is, it is the difference in electrical potential that exists between two specific points.

To understand and be clear: one, therefore, is a voltage term and the other is a power term.

In the same way, we cannot ignore that watt is a word that is widely used within the field of sport and, more specifically, in the world of cycling. In this sector it is used to refer to the measure of power that comes to record the force that the rider exerts to be able to move his bicycle. In order to know the aforementioned force, it is usual for electronic devices to be placed in the area of ​​the transmission in particular in the two-wheeled vehicle.

Such items can be installed on pedals, cranks and even axles, which are identified because they have great reliability in terms of the results they offer.

In order to determine the meaning of the term vainglory, the first thing we are going to do is know its etymological origin. In this sense, we can state that it is a word that derives from Latin. Specifically, it is the result of the sum of two components of that language: -The adjective “vanus”, which can be translated as “empty”. -The noun "glory", which is equivalent to "fame", "honor" or "splendor". Boasting is the petulance or presumption of an individual regarding his actions or self- worth . The verb boast alludes to this act of boasting. For example: "I am fed up with the pride of this artist: he may have a lot of talent, but he lacks humility" , "I don't understand your pride: you have just made a big mistake and yet you are proud of your actions" , " You should not act out of pride, but out of solidarity ” . The term boastful, therefore, is also a conjugation of the verb boast: "The o

ABBOT

Abad is a concept that, according to what is detailed by the dictionary of the Royal Spanish Academy ( RAE ), comes from abbas , a Latin word. The term refers to the religious who occupies the superior position in a type of monastery known as an abbey . The abbot, therefore, is the spiritual father, leader and person in charge of an abbey . In its origins, the notion was not linked to a hierarchy or a formal position, but was an honorary title . The honor arose in Syrian monasteries and then began to be implemented in Europe. Regarding the way in which the abbots lived before the formal organization, it is known that they were hermits, who, through their acts and customs, pursued a state in which their spirit was liberated from the material world. It was precisely thanks to this discipline that they could achieve a degree of knowledge and harmony that attracted other religious to congregate around them. Far from being a selfish attitude or a symbol of lack of concern for the rest o

VARIABLE

Derived from the Latin term variabilis , variable is a word that represents that which varies or is subject to some type of change. It is something that is characterized by being unstable , fickle and changeable . In other words, a variable is a symbol that identifies an unspecified element within a certain group. This set is usually defined as the universal set of the variable ( universe of the variable , on other occasions), and each piece included in it constitutes a value of the variable. For example: x is a variable in the universe { 1 , 3 , 5 , 7 }. Therefore, x can be equal to any of the values ​​just mentioned, with which it is possible to replace x with any odd number that is less than 8 . As you can see, variables are elements present in formulas, propositions and algorithms, which can be substituted or can acquire, without ceasing to belong to the same universe, different values. It is worth mentioning that the values ​​of a variable can be framed wit
