Question:medium

In a neon discharge tube, $ 2.9 \times 10^{18} \, \text{Ne}^{+} $ ions move to the right each second while $ 1.2 \times 10^{18} $ electrons move to the left per second, electrons charge is $ 1.6 \times 10^{-19} \, \text{C} $. The current in the discharge tube is:

Show Hint

The current in a discharge tube can be found by summing the individual currents due to ions and electrons, considering the direction of their movement.
