In a hydrogen discharge tube, the number of protons drifting across a cross-section per second is 1.0 x 1018, while the number of electrons drifting in the opposite direction across the same cross section is 2.9 x 1018 per second. Find the current flowing in the tube. (charge on each electron is 1.6×10−19 C)​

Explanation:

Solution :

As electrons and protons are moving in the opposite

directions, they will effectively produce current in the same

direcition and the total current in the tube is

I=(np+ne)e/t

=(1.0×1018+2.7×1018)×1.6×10-19/1

=3.7×1.6×10-1A=0.592A
