Pendant as unit of measure:

The Coulomb – unit of electric charge (quantity of electricity), as well as the flow of electric induction (flux electric displacement) in the International system of units (SI), named in honor of in honor of the French physicist and engineer Charles Coulomb.

The Coulomb as the unit of measurement is the Russian designation – TC and international designation – S.

1 Coulomb is defined as the amount of charge passing through a conductor when a current of 1 ampere during 1 second.

KL = A · s.

1 C = 1 A · s = 1 / 3600 ampere-hours.

Charge of one Coulomb is very large. If two carriers of the charge (q1 = q2 = 1 C) placed in vacuum at a distance of 1 m, they interacted with the force of a 9⋅109 H, that is, with the force with which the gravity of the Earth attracts the object with a mass of about 1 million tons.

Electric charge (quantity of electricity) is a physical scalar value. Carriers of electric charge are electrically charged elementary particle (electron, positron, proton, etc.). The lowest mass stable in the free state of the particle with one negative elementary electric charge is the electron. The electric charge of the electron is indivisible and equal -1,6021766208(98)⋅10-19 Coulomb. The charge of the proton, also equal to the charge of the electron, but with opposite sign (+sign) and equal to +1,6021766208(98)⋅10-19 Coulomb.

Thus, the elementary electric charge (up to a sign equal to the electron charge or the proton) is the above value +/- 1,602176 6208(98)⋅10-19 KL. Accordingly, the electric charge 6,24151⋅1018 electrons is -1 CR and the electric charge 6,24151⋅1018 protons are +1 CL. The mass of the electron is 9,10938356(11)⋅10 -31 kg, proton 1,672 621 923 69(51)⋅10-27 kg.

The lowest mass stable in the free state of the antiparticle with positive elementary charge – the positron, having the same electric charge as the electron but with + sign. The electric charge of the positron is +1,6021766208(98)⋅10-19 Coulomb. The mass of the positron 9,10938356(11)⋅10-31 kg.

In the International system of units pendant introduced by the decision of the XI General conference on weights and measures in 1960, simultaneously with the adoption of the SI as a whole. In accordance with the rules SI, and relating the derived units are named for scientists, the name of the unit “pendant” is spelled with a lowercase letter and its name — capital (KL). Such writing of the designation is stored in the symbols for derived units formed by using a pendant.

 

The use of pendant:

In coulombs measure electric charge (quantity of electricity), the flow of electric induction (flux of electric displacement).

 

The presentation of the pendant in other units – of the formula:

Through the basic and derived SI units, the Coulomb is expressed as follows:

KL = A · s

where KL is the Coulomb, And ampere, with the second.

 

Multiple and fractional units of Coulomb:

Multiple and sub-multiple units are formed using standard prefixes of the SI.
