Question

A conductor carry a current of 0.3 amphere.. Find the amount of charge following in 30 sec...How many electrons are passing through any across of conductor...​

Answer 1

Current :- 0.3A

time = 30sec

Now ,

Current = No of electrons/ time

Current = ne /time

0.3A = n/30sec

ne = 9 C

n ×1.6×10^-19C = 9C

n = 9/1.6×10^-19=5.62×10^19

Answer 2

Answer:

I=q/t

=0.3=q/30

=0.3×3=q

=0.9C=q
