What is the radius of 1 coulomb?

Answer 1

A coulomb is a unit of charge. In other words, it's a certain number of electrons, specifically 6.24145 x 1018. It can't be given a radius, much like you can't give a radius to a dozen of cookies.

Answer 2

The Coulomb is the SI unit of electric charge. There are several ways to think of it.

It's the amount of charge that:

- pours out of a battery every second when the current is 1 Ampere.

- has to flow through a solution of silver nitrate to deposit

0.001118 gram of silver on the spoon.

- on one plate of a 1-Farad capacitor when the voltage across

the capacitor is 1 volt.

- on 6,218,220,000,000,000,000 electrons or protons.

(6.218 x 1018 , rounded)

Answer 3

The concept of radius is typically used in relation to circles and spheres, not in terms of electric charge. The unit "coulomb" refers to the amount of electric charge. It does not have a radius.
