# If the Charge on an Electron is 1.6 × 10−19 Coulombs, How Many Electrons Should Pass Through a Conductor in 1 Second to Constitute 1 Ampere Current? - CBSE Class 10 - Science

#### Question

If the charge on an electron is 1.6 × 1019 coulombs, how many electrons should pass through a conductor in 1 second to constitute 1 ampere current?

#### Solution

Given:

Current,/=1A

Time,t=1s

Using the formula:

I=Q/t

or,

Q=Ixxt

=1xx1

=1=C

Now, if the charge is 1.6xx10^-19C, the number of electrons is 1.So, if the charge is 1C, the number of electrons is given by:

1/(1.6xx10^-19)xx1=6.25xx10^18

Thus, 6.25xx10^18electrons should pass though a conductor in 1 second to constitute 1 ampere current.

Is there an error in this question or solution?
