In a Neon discharge tube 2.9 x 10^18 Ne^+ ions move to the right each second, while 1.2 x 10^18 electrons move to the left per second,

Question 1

In a Neon discharge tube 2.9 x 1018 Ne+ ions move to the right each second, while 1.2 x 1018 electrons move to the left per second, electron charge is 1.6 x 10-19 C. The current in the discharge tube is

(a) 1 A towards right

(b) 0.66 A towards right

(c) 0.66 A towards left

(d) zero

Question 2

The correct option is (b) 0.66 A towards right.

Explanation:

The direction of current in a circuit is, by convention, taken along the direction in which positive charges flow. Hence the current in the discharge tube flows towards right.
