Question

What is current in a gas discharge tube if 3.0 x 1017 electrons and 2.0 x 1016positive ions pass through a cross-section of the tube each second?

Answer 1

As,
I=Q/t
where,
Q=ne
here,
n=3*10^17
and
e=1.67*10^-11
and here t=1


As we know that current is the flow of electrons then we will consider only -ve particles not +ve particles


then I=(3*10^17)*(1.67*10^-11)/1
answer is 5010000coulombs

Answer 2

Thanks :)
