Which is bigger, a coulomb or charge ona n electron?

Define one coulomb charge.

How much energy is given to each coulomb of charge passing through a 6 V battery?

What is the value of charge on electron? Is a charge less than this value possible?

In an electric field the work done in bringing a 2 coulomb charge from infinity to a point a is 10 joules and in bringing the same charge to some another point B is 20 joule find the potential difference between two points A and B what would be the work done if the same charge is brought directly from A to B.

Who determined the charge on the electrons ?

If a charge is moved against the Coulomb force of an electric field
