Question

how many electrons in 1
S constitutes a current of 1A​

Answer 1

An electron has a charge of 1.60 x 10^-19 coulombs, so it takes 6.25 x 10^18 electrons to make up 1 coulomb of charge. 

Answer 2

One ampere is one coulomb of current per second.

One coulomb contains 6.25 × 10^18 electrons.

This is because,

Q = ne,

• n is the no of electrons
• Q is the charge =1C
• e is the charge of electron = 1.6 × 10^-19

On substituting all these values, you will get

n = 6.25 × 10^18 electrons.

This is your answer
