In a hydrogen discharge tube, the no. of protons drifting per second across a cross-section is 1 x 10 to the power 18, while the no. of electrons drifting per second in the opposite direction across another cross-section is 2.7 x 10 to the power 18. Find the current flowing in the tube. If the voltage appplied across the tube is 220V, find the effective resistance of the tube.
