Question

Calculate the number of electrons constitute current of one ampere ​

Answer 1

Answer:

An electric current of 1 ampere is equal to 1 coulomb of charge passing a point in a circuit every second: Therefore a current of 1 ampere = 6.242 × 10^18 electrons moving past any point in a circuit every second.

Answer 2

I = dq/dt

1 A = 1 C per second

1 electron's change = 1.6 x 10^-19 C

so one coulomb = 1 / e =  6.22 x 10^18 electrons

therefore 1 A = 6.22 x 10^18 electrons flowing per second
