Amperage: what it is, how it is measured and difference with voltage

In common opinion, two terms, such as amperage and voltage, or amps and volts, are often confused and identified as synonymous with current, but they are actually units of measurement that refer to different electrical quantities. So let’s get to know the amperage better: what it is, how it is measured and it differs from the voltage Amperage: what it is, how it is measured and it differs from the voltage The misunderstanding often arises from the fact that even two words like voltage and current are often used incorrectly and without any distinction, so it is necessary to clarify the definition of the two terms before understanding the real difference between amperage and voltage. Current and voltage: definitions and differences. Current is the number of charges that flow between two points inside a conductor in a precise time interval, therefore, the higher it is, the more the electric charges will move from one pole to the other.Each body is made up of atoms and receives a force from the inside, coming from them electrons, which, in turn, receive a push or force from the outside that allows them to move from one atomic nucleus to another, giving life to flows called electric current. Arga or negative pole and the positive pole of a conductor, called the potential difference (or ddp) is what determines the passage of the electric current, whose unit of measurement is represented by the Ampere, indicated with the symbol A. Such potential difference Between two points internal to an electric field, voltage is defined and it is expressed in volts, units of measurement represented by the symbol V. In a common electrical outlet it is not possible to identify the real current but there is the voltage that originates it, which is usually around 220 volts.Obviously, the amount of current generated can be variable in relation to the resistance it encounters, in fact we could say that the higher the resistance, the lower the current flow through the interior of a body. The current flow also divides the materials into different ones. types, conductors and insulators. The former identify those that favor the passage of electricity thanks to the freedom of movement of the electrons, while the latter, on the contrary, make it difficult for the electrons to move freely. The relationship between two electrical quantities such as current and voltage and the one with resistance is defined by a formula, called Ohm’s Law, which establishes the relationship between three electrical quantities, two are precisely current and voltage, the third is resistance What is the difference between volts and amps? Having clarified the concepts of current and voltage, it will be natural to understand the difference between amperage and voltage, which are nothing more than the respective units of measurement of the two quantities, as we have seen. Specifically, volts, that is, voltage is the electrostatic force of an electric field. In the case of electrical energy, the electromotive force, that is, the force applied to a body, can also be measured in volts. However, unlike the volt, the ampere refers to the electrical intensity, understood as the quantity of charges moving within a conductor. Broadly speaking, we can say that voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons.An electrical current at 1000 volts is not more deadly than a current at 100 volts, but small changes in the amperage could mean that if we suffer an electrical shock, the risk of dying from it may or may not be high .. Although the physics is complicated , we can use the analogy of a flowing river to explain the principles of electricity and thereby finish understanding how amperage differs from voltage. In this analogy, the voltage would be the slope of the river, while the amperage is the volume of water in the river. An electrical current with high voltage but very low amperage can be a small and very narrow river that flows almost vertically, like the small flow of a waterfall. It would have little potential to harm us. But a large river with a lot of water (amperage) can drown us even if the speed of flow (voltage) is relatively slow.
