Question

Find current when 100 million electron flow through a cross section of conductor in 1 microsecond

Answer 1

Hi mate

Here is the answer

We know,

number of electrons =100million

=100*10^6

e(charge on one electron) =1.6×10^-19C

Time(t )=1 microsecond =1*10^-6 second

Now, current, I=Q/T

= I =n×e/t

=I=100×10^6× 1.6×10^-19/1×10^-6

=I=1.6×10^-5 A

= I=16mu A
