Question

if a current 3.2 ampere per second flows through a conducting wire calculate the number of electron passing through a wire? ​

Answer 1

$\huge\mathtt{\underline{Solution}}$

The current is defined as rate of flow of charged particle.i.e.

i =tQ

Hence the charge flown is,

Q =i t

Hence Q =1.0×1=1C

The charge Q is due to electrons, therefore,

Q =N×e

Here Q =1C

If N is number of electrons passing and e is the electronic charge of value 1.6×10−19

Then,

N =eQ=1.6×10−191=0.625×1019electrons

Answer 2

Answer:

N=eQ=1.6*10-191=0.625*1019 electrons
