Q. A flow of $10^6$ electrons per second in a conducting wire constitutes a flow of current of

KEAMKEAM 2015Current Electricity

Solution:

Given, $n=10^{6}$ electron per second
We know that, $q=$ ne
$q=10^{6} \times 1.6 \times 10^{-19} C$
Now, as the flow charge is
$1.6 \times 10^{-13}$ coulomb per second
So, $i=1.6 \times 10^{-13} A$
