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^-19`C, 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, `6.25xx10^18`electrons should pass though a conductor in 1 second to constitute 1 ampere current.

  Is there an error in this question or solution?
