Question

Give the relationship between electric current, number of electrons moving in a circuit and time in SI unit.​

Answer 1

Answer:

Since charge is measured in coulombs and time is measured in seconds, an ampère is the same as a coulomb per second.

Answer 2

Explanation:

Each electron has a charge. The current is equal to the charge per unit time. If one coulomb of charge passes a point over 1 second, 1 amp of current is flowing.

We can calculate the charge(Q) by multiplying the number of electrons by the charge on an electron:

Q = ne

We can then calculate the current:

I = Q/t

I = (ne)/t
