Question

What does the unit for electric current mean? It's Newtons per Coulomb, and I don't understand what that means. For example, velocity is meters per second, it tells me how far something travels in a second. An electric field is a measure of how much force per charge? I don't grasp the meaning of that in the same way, anyone able to explain it simply?

Answer 1

The unit for electric current is the ampere, which is \(C \over s\). The units \(N \over C\) is the units of electric field. This further simplifies to \(V \over m\). This means that the force between two point charges divided by the charge of these point masses gives us the strength of the electric field.
