Question

the charge on an 2 is 1.6 ×10power _19. find the number of electron that will flow per second to constitute a current of 2A.

Answer 1

I= 1 A

q= 1.6*10-19C

t= 1 s

so, I=ne/t == 1=n(1.6*10-19C)/1

= n= 1/1.6*10-19

= 1019/1.6

=(10*1018)/1.6

=6.25*1018.

Answer 2

it is correct answer
