AIIMS 2000 Physics Electric Current MCQ Question
Type: MCQ-numerical-Medium-Class 12
In a Neon discharge tube 2.9 × 10¹⁸ Ne⁺ ions move to the right each second, while 1.2 × 10¹⁸ electrons move to the left per second, electron charge is 1.6 × 10⁻¹⁹ C. The current in the discharge tube is
A
1 Å towards right
B
0.66 Å towards right
C
0.66 Å towards left
D
zero
Correct Answer
Option B
Detailed Explanation
The current is calculated by considering the net charge flow per second. The total charge flow is the sum of charges due to ions and electrons, resulting in a current of 0.66 Å towards the right.
