Asked by El chapo
A high potential is applied
between the electrodes of a
hydrogen discharge tube so
that the gas is ionised.
Electrons move towards the
anode and protons towards the cathode. In each second,
5x10^18 electrons and 2x10^18
protons traverse a cross
section of the tube. What is the
current flowing in the discharge
tube? (Take charge of each electron
and proton = 1.6x10^-19C)?

a proton moving one way is the same current direction as an electron moving the opposite way so add absolute values
7 * 10^18 particles/second * 1.6*10^-19 coulombs/particle
7 * 10^18 particles/second * 1.6*10^-19 coulombs/particle
