The dictionary of the Royal Spanish Academy (RAE) defines the voltage as the amount of volts acting on an appliance or electrical system. In this way, the voltage, which is also known as tension or potential difference, is the pressure that a supply source of electric power or electromotive force exerts on electric charges or electrons in a closed electrical circuit. This is how the flow of an electric current.

The greater the potential difference exerted by a source of electrical energy supply, the greater the voltage in the circuit to which that conductor corresponds. The potential difference is measured in volts (V), as is the potential.

The voltage between two points of an electric field is equal to job carried out by said unit of positive charge to transport it from point A to point B. It should be noted that the voltage is independent of the path traveled by the charge, and depends exclusively on the electric potential of points A and B in the country.


Voltage refers to the number of volts.

Electric current and induced voltage

When two points that have a potential difference are joined through a driver, there is a flow of electric current. Part of the charge that creates the point of highest potential is transferred by the conductor to the point of lowest potential; in the absence of an external source (a generator), the current ceases when both points equal their electric potential. This transfer of loads is known as electric current.

All of this also leads us to refer to what is known as induced voltage. A term that is used to refer to the force that has the ability to produce, in a closed circuit, electric current. However, this concept is also used to refer to the force that, in an open circuit, is capable of maintaining the electrical voltage between two specific points.

Voltage is also known as voltage.

The concept in colloquial language

In addition to all the above, we cannot ignore the fact that voltage is also used in colloquial language. Specifically, we speak of high voltage, an expression that tries to define that a specific situation is loaded with action or eroticism and sexuality.

A phrase that can work as a perfect example of this meaning that we are citing is the following: Luis and Manuela had a high-voltage date where caresses and kisses were the absolute protagonists.

In the same way, we also have to mention that there are several films that use the term that we are analyzing in their titles and specifically with the last used meaning. Among those stands out, for example, the Spanish production “Isi & Disi, Alto Voltaje”. In 2006 this film was released, directed by Miguel Ángel Lamata, which tells us the story of two friends who are absolute fans of the AC / DC group and who must get a rock group to win a contest to be able to face to some outstanding debts.
