Question

A current of 0.5A passes through a conductor for 2s. How many electrons flow through any cross section of the conductor during this interval ?

Answer 1

First of all we can write the given information

=> I= 0.5 A

=> T= 2s

Given ,...the charge on each electron = 1.6 x 10^-19C

We can apply the formula

I=ne/t

That => n=it/ e

So, 0.5 x2/1.6 x10^-19

N= 6.25x10^8

this is your answer

Answer 2

Hi mate here u go

I=0.5

T= 2 sec

E = 1.6 x 10^-19'

Why have n= it/e

N= 0.5x2/1.6x10^-19

N= 6.25x 10^8
