Question

How many electron pass 2minutes into if the current passing throw wire 300

Answer 1

HOLA AMIGO!!

HERE WE GO

GIVEN

Current = 300A

time (t) = 2min = 2×60 =120s

SOLUTION

we know I = Q/t = ne/t
where n = no.of electron and e= charge of electron = 1.609×10^-19

I = ne/t
n = It/e

= 300×120/1.609×10^-19

=36000/1.609×10^-19

= 3.3676
therefore n = 3.3676


HOPE IT'S HELPFUL

Answer 2

q = it
q= ne
it = ne
n = it/e
n = 300*2*60/1.6*10^-19
n = 36* 10^22/1.6
n = 9*10^22/.4 = 90/4*10^22 = 22.2*10^22 electrons...
