Question

In gases the flow of current is due to    A. Electrons only  
 B. Positive ions only    
C. Electrons and positive ions    
D. Electrons, positive ions and negative ions​

Answer 1

Answer:

answer option D

Explanation:

Current in gases and liquids generally consists of a flow of positive ions in one direction together with a flow of negative ions in the opposite direction. To treat the overall effect of the current, its direction is usually taken to be that of the positive charge carrier

Answer 2

In this question, we are asked to tell the current flow in gases due to what.

• Option D is the correct answer i.e., Electrons, positive ions, and negative ions.
• In gases the flow of current is due to electrons, positive ions, and negative ions​.
• Positive ions flow in one direction and negative ions flow in the opposite direction to make up current in gases and liquids.
• Its direction is typically assumed to be that of the positive charge carriertoo treat the current's overall effect.
• Atmospheric pressure gases are not very effective electrical conductors.
• Therefore, a unique device known as a gas-discharge tube is needed to transfer a current through a gas.
• Two electrodes are typically sealed through the walls of a glass tube that serves as a gas discharge tube.
