Question

A steady current of 1 ampere flows through a conductor. Calculate the number of electrons that flows through any section of the conductor in 1 second

Answer 1

6.25 × 10^18 is the number of electrons flowing in the conductor.

Explanation:

current = charge / time

1 Ampere = charge / 1 sec

charge = 1 Coloumb

or charge = n×e

e = n × 1.6× 10^-19

now, 1 Coloumb = n × 1.6 × 10^-19

After calculating we get

n = 6.25 × 10 ^ 18 electrons

'n' is number of electrons

'e' is charge of an electron
