The concept of Latin origin resistance It still has relevance since its meaning is exploited from various fields. In this context, it can be emphasized that the word resistance it has definitions from the perspective of the physical , the engineering , the psychology , the medicine and the geography .
We can name as an example the electric resistance of a certain substance, which is defined as the opposition found by the electric current when it enters circulation. Its value is designated in ohms. On the other hand, it is known as resistance or resistor to the electronic part that has been manufactured to generate a specific electrical resistance between two points of the same circuit.
All objects, whatever their material, offer a less or greater resistance for the passage of electric current. Among the metals, those with the least resistance are silver and gold; The reason why the conductors that are used inside the cables are made of copper is because it would be extremely expensive to manufacture them from gold or silver and in addition, copper is also a very good driver and clearly, much cheaper.
In some cases the aluminum As a conductor in the cables, for example in those of high voltage towers, it is usually used especially when it is necessary to transport electricity over very long distances.
Other materials that can serve as good electricity conductors are the nichrome wire (Ni-Cr), ideal for regulating the voltage in some electrical devices; It also serves to produce heat in certain industrial equipment and appliances (stoves, irons and heaters).
He carbon It can also be used to make resistors that serve to regulate the values of the current and the voltage in the electronic circuits .
The resistance of an element , on the other hand, it has to do with the ability of a solid to withstand pressures and applied forces without breaking, deforming or deteriorating.
The physical resistance , on the other hand, is a capacity of the human body (which allows to develop an activity for a prolonged time). In this way, the endurance races they constitute a car and motorcycle discipline in which the level of the cars and the capacity of the pilots are measured physically.
In this resistance the central organ is the heart , which allows the body to keep moving by pumping the blood that will reach every corner of the body, that blood is the energy that allows the development of the functions of each muscle of the body. The heart and lungs , responsible for providing oxygen, are the essential organs for the production of physical resistance .
With regard to the use of the term in the functioning of living organisms, it should be noted that there are two types of resistance, the general psychic resistance (capacity that makes it possible to make a hard training for as long as possible) and physics (the body's ability to resist the fatigue that a given activity can generate).
In turn, it can be divided in many ways, from the muscular aspect (general global or local resistance), from the muscular energy metabolism (general aerobic or anaerobic resistance), from the duration of the effort (short, medium or long-term general resistance) and from the perspective of the motor solicitation forms (general resistance, strength, general explosive or general resistance-speed).
For psychology, resistance is a attitude that opposes the therapeutic approach . A resistance behavior is an opposition behavior that an individual adopts against another (or others), which can have a positive or negative value.
In the social sciences, resistance implies the rejection of a person to the practices that so far have allowed her to think about herself. Thus resistance implies an individual or collective search for other practices.
Finally, we can mention that Resistance It is the capital of the Argentine province of Chaco .
