How many electrons are there in 1 coulomb of charge? - 1 coulomb
And please, please help them. The attempt, on the Internet for books and other teaching. Thank you.

1 Coulomb How Many Electrons Are There In 1 Coulomb Of Charge?

If the charge is the electron e = 1.6021176462 x 10 ^ -19 C. Then, in 1 coulomb of charge: --
Number of electrons x = 10 1/1.6021176462 ^ -19
What is 6.241509745 x 10 ^ 18 electrons.
Given the force between two point charges Q1 and Q2, separated by a distance of r''is Coulomb's law: --
F = ... 1. Q1.Q2
......__. ____
..... 4πε0. R ²
Substituting the values of this formula: --
F = 10 ^ -6 x 10 ^ -6 / (4 x 3.14 x 8854 x 10 ^ -12 x 0.2 ²)
Therefore F (= 0.2247 N to 4 DP rounded) (Use the constants in the pc-systems πε0)
A coulomb is the quantity of goods produced by one ampere in one second, the amounts of 6.24 * 10 ^ 18 electron charges.
Just to clarify, a coulomb is neither positive nor negative, it is only a scalar charge. This means a coulomb of charge can of protons or electrons (positrons and antiprotons exist). 5C, if anything, you have, if 5 or C-5C say
Because David was probably right.
