Question

9ma electric current is flowing through a conducting wire then number of electrons passing through it

Answer 1

Answer:

5.6*10^16 electrons per second

Explanation:

I = 9 mA = 0.009 A

1 ampere means 1 C of charge flows through it per second.

0.009 ampere means 0.009 C of charge flows through it in one second.

1 coulomb charge is present on 6.24 * 10^18 electrons

0.009 coulomb charge is present on 0.009*6.24*10^18 electrons

After simplification, the answer is 5.6*10^16 electrons per second.
