Just like the answer to mole is amount of atoms in 12 grams of carbon12. I wonder, is there a reason behind the amount of electrons in a coulomb?
Amok said:What Nabeshin said is correct. Did you know that the ampere is a fundamental base unit in the SI system and the Coulomb is not? Funny huh?
Amok wasn't trying to say they are the same. The thing is, we are free to choose one quantity, and only one, in electromagnetism for the purpose of defining all electromagnetic units. Much as one defines the meter, second, and kilogram as base units, and then the units for velocity (m/s), force (Newtons = kg*m/s2), etc. are all defined in terms of just the base units.Femme_physics said:Well, they don't really represent the same thing if I got it right. Coulomb is an amount, regardless of time. Whereas ampere is an amount with respect to time. So, they're not really convertible I think.
Actually, she wasn't really asking about the mole. Just using it for comparison purposes, asking if there was perhaps a similar relation between the Coulomb and the electron charge. At least I think that was Femme_physics's intent.Amok said:And about the mole question, you answered it yourself...
One coulomb is equal to 6.241 × 10^18 electrons because of the fundamental charge of an electron, which is 1.602 × 10^-19 coulombs. This means that to make one coulomb of charge, it takes a large number of electrons, in this case 6.241 × 10^18.
The value of one coulomb was determined through experimentation and measurement. Scientists conducted experiments to determine the amount of charge carried by a single electron and then used this value to calculate the number of electrons needed to make one coulomb of charge.
Yes, one coulomb of charge is always equal to the same number of electrons, which is 6.241 × 10^18. This is because the fundamental charge of an electron is a constant value and cannot change.
The coulomb is a unit of measurement for electric charge. It is used to measure the amount of charge that is flowing in an electric circuit or stored in an object. The larger the number of coulombs, the greater the amount of electric charge present.
Yes, one coulomb of charge can be divided into smaller units such as milli-coulombs or micro-coulombs. This is similar to how we can divide one meter into centimeters or millimeters. However, the fundamental charge of an electron will always remain the same, regardless of the unit used to measure it.
