What is a direct current?
The direct current is a form of electric current used in direct current (DC) and consists of electrons that move continuously in one direction. This is, unlike AC current (AC) of electricity in which electrons move first in one direction, then in the opposite direction and alternate between each of them. DC electricity is often used in batteries and similar forms of electrical power sources, because it is usually easy to create a circuit using DC electricity, although electricity AC is often preferred over long distances. The direct current is one of the simplest forms of electric current to be understood, and is often used to explain how electricity works. The current consists of a current of negatively charged electrons via the system, and in a direct current, this electronhgh flows in one direction. Electric charges flow from one charge to another, "opposites attract" as they say, and so negatively charged electrons naturally flow towards the possessionItally charged areas.
The direct current flows through the circuit by means of a conductor, which is a material, often metal, which naturally provides a condition in which electrons can easily move. The conductive materials often work on the transmission of energy of any type, whether it is heat or electricity, so the metal surface will usually be hot faster than a non -conductive surface and will also perform electricity. This type of circuit is created by combining the negative and positive part of the energy source, such as the battery, at both ends of the perimeter.
direct current flows from the negative end, through the perimeter and eventually reaches a positive end. By placing something that can take advantage of the charge, for example Ana the circuit is transferred to the item when it passes towards the positive end, the perimeter is transferred to the perimeter, perimeter, perimeter, charging. Many diagrams of circuits show the charge that flows from a positive end towards the negative end; ItHowever, it is not accurate and is often done as part of an old convention that is still used despite its inaccuracy.
AC current, on the other hand, still flows from the negative to positive, but polarization changes and repeatedly switches during the use of the perimeter. This means that the flow can occur from left to right, but then it will switch to move from right to left. The alternating current voltage is easier to change using transformers, so alternating electricity is often better at long distances, such as between the power plant and the home or the company. Direct current is usually used in batteries and power sources that travel for shorter distances because it does not require polarization changes and can be easily integrated into a smaller circuit.
