What is Coulomb?

Coulomb is an electric charge level and is defined as a charge that flows with a constant current of one ampere (1 amp) in one second. The fee can be either positive or negative. It is equivalent to 6.241 x 10 18 electrons. The idea of ​​Coulomb is useful in electrochemia and physics. In this analogy, the AMPS or apege is the speed of water and Coulomb is the amount of water transported in a given time period. In everyday circumstances, most people are interested in the tension required by the device or with the power of the replacement bulb. The actual flow of the charge or used Coulamby is only important if it is time to pay an electricity account.

The electric charge is not the same as the electron. The electron is a subatomical particle that carries a charge. In a piece of metal, the electrons are relatively freely held in the proton pkrajka, a positively charged atom core. Once the potential or voltage is applied, the electrons move in a uniform way and the charge is transmitted if there is a difference between the end of the metalLike a river, a vertical drop requires a flow.

Since the charge of one Coulomb is the equivalent sum of the cartridges of 6.241 x 10 ^{18 , the charge on one electron is divided by 6.241 x 10 18 electrons into Coulomb. Charging on one electron is 1.602 x 10}

-19 Coulombs. Robert Milikan won the 1923 Nobel Prize for his work when measuring the electron hub.

The best known charge transmission occurs in the electric circuit of the household. The metal conductor, usually a copper wire, is used to transmit electricity from the delivery of the house to light. When the light switch is on, the lights are immediately. This happens because the charge actually moves faster than electrons. It also moves in the opposite direction.

Some fees for the transmission of solids as a positively charged protons. Sometimes the carriers of the hubs of these solids are described as electron openings nobo where there should be electrons. The semiconductors used in electronics are often made of positive materials transmitting hubs. In these materials, the charge moves in the same direction as the hub carriers. Electrolyte solutions, solutions of dissolved minerals or other substances carry recruitment in two directions, because the negatively charged ions travel in one direction and the positive ions will travel the opposite.

Coulamby are used in calculations involving electrochemics and physics by electricity and magnetism. A joint problem with chemistry in high school will ask how much metal is placed on a substrate in a metal plating bath, due to current and time currje applied. The problem of physics using Coulomb can be addressed by the efficiency of a photovoltaic panel that converts photon energy into electricity.
