# What is Voltage?

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

The greater the potential difference exerted by an electrical power supply, the greater the voltage in the circuit to which that conductor corresponds. The potential difference is measured in volts (V), just like the potential.

The voltage between two points of an electric field is equal to the work done 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 taken by the charge, and depends exclusively on the electric potential at points A and B of the field. All this also leads us to refer to what is known as induced voltage. Term 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 able to maintain the electrical voltage between two specific points. When two points with a potential difference are joined by a conductor, an electric current flows. Part of the charge that creates the point of higher potential is transferred by the conductor to the point of lower potential; In the absence of an external source (a generator), current ceases when both points equal their electrical potential. This transfer of charges is known as electric current. In addition to all this, we cannot ignore the fact that voltage is also used in colloquial language. Specifically, we talk about high voltage, an expression that tries to define that a certain situation is loaded with action or eroticism and sexuality. A sentence that can work as a perfect example of this sense that we are quoting is the following: Luis and Manuela had a high-tension encounter where caresses and kisses were the absolute protagonists. Likewise, we must also mention that there are several films that use the term that we are analyzing in their titles and, specifically, with the last meaning used. Among them, for example, the Spanish production “Isi & Disi, Alto Voltaje” stands out. It was in 2006 that this film was released, directed by Miguel Ángel Lamata, which tells the story of two friends who are absolute fans of the AC / DC group and who have to get a rock group to win a contest to be able to face it. to some debts they have outstanding.
