subject: Number Of Electrons In One Coulomb [print this page] Coulomb is the S.ICoulomb is the S.I. unit of the quantity of the charge. As we know that, the elementary charge is the charge of one electron. Charge is the inherent property of the material, which is due to the transference of electrons. Charges are of two types. One is the positive charge that is due the deficiency of electrons and the other is negative charge that is due to the extra electrons. Here we discuss that how many electrons are there in one coulomb.

Let us Find out the Number of Electrons in One Coulomb
To find out the number of electrons in one coulomb of charge we made some calculations. The charge on one electron is 1.6 10-19 Coulomb. The total charge is one coulomb. The formula to find the number of electrons is follows:
Number of electron in given quantity of charge = Total charge / the amount of charge on one electron
The number of electrons in one coulomb charge = 1 / (1.6 10-19)
Thus, the number of electrons in one coulomb of charge is 6.25 1018 approximately. The number is very large that means there are lot of electrons in one coulomb of charge.
Conclusion to the Number of Electrons in One Coulomb
Generally when we talk about the charge or the electric current the mostly we discuss about the electron. The reason behind this is the electron is the elementary particle or it is responsible to the flow of electric current in any conducting wire or in any circuit. The elementary particle means there is no any existence of such a particle whose charge is less than the charge of one electron. The amount of charge passing through any circuit or through any conductor is called the electric current. The electric current measures in Ampere. The direction of the flow of electric current is opposite to the flow of electrons, which are negatively charged, and the direction of flow of electric current is same as that of the protons, which are positively charged.
This SI unit is named after Charles-Augustin de Coulomb. As with every International System of Units (SI) unit whose name is derived from the proper name of a person, the first letter of its symbol is upper case (C). However, when an SI unit is spelled out in English, it should always begin with a lower case letter (coulomb), except in a situation where any word in that position would be capitalized, such as at the beginning of a sentence or in capitalized material such as a title. Note that "degree Celsius" conforms to this rule because the "d" is lowercase. Based on The International System of Units, section 5.2.[2]
