Explaining Why Gas Conducts Electric Fields

The movement of the gas particles is driven by the force equation F=QE, where F is the force, Q is the charge, and E is the electric field strength. The gas needs a minimum amount of force to move from one end of the tube to the other, which is why it only becomes conducting at a certain electric field strength. In summary, the gas in the tube becomes conducting when the electric field reaches a certain value due to the force equation F=QE.

Homework Statement


Explain why the gas becomes conducting only when the electric field in the tube reaches certain value?
2) why does fields does from higher potential to lower potential?

Homework Equations


F=QE

The Attempt at a Solution


If we increase the E then the Force will also increase so I think the gas needs certain amount of force for it to move to other end. I am not sure If I am right.

The problem statement is incomplete. What gas? What tube?
 
  • #3
A certain gas in a tube is subjected to an electric field of increasing strength. The gas becomes conducting when the electric field reaches a strength of 35NC^-1
 

FAQ: Explaining Why Gas Conducts Electric Fields

1. What is the relationship between gas and electric fields?

Gas molecules have charged particles (electrons and ions) that can be affected by electric fields, causing the gas to conduct electricity.

2. How does gas conduct electricity?

When an electric field is applied to a gas, the charged particles within the gas are accelerated, causing them to collide with other particles and transfer their charge. This movement of charged particles allows the gas to conduct electricity.

3. What factors affect the ability of gas to conduct electricity?

The density of the gas, the strength of the electric field, and the temperature of the gas can all affect its ability to conduct electricity. Higher gas density, stronger electric fields, and lower temperatures generally result in better conductivity.

4. Why do some gases conduct electricity better than others?

The ability of a gas to conduct electricity depends on its composition and the availability of charged particles. Gases with a higher proportion of charged particles, such as ions, will conduct electricity better than gases with fewer charged particles.

5. Can gas conduct electricity in all types of electric fields?

No, gas can only conduct electricity in the presence of an electric field. Without an electric field, the charged particles in the gas are not in motion and are not able to transfer their charge, thus not conducting electricity.
