Explaining Why Gas Conducts Electric Fields

Click For Summary
SUMMARY

The discussion centers on the conditions under which a gas becomes conductive when subjected to an electric field. Specifically, the gas transitions to a conductive state when the electric field strength reaches 35 N/C. The relationship between electric field strength and force is defined by the equation F = QE, indicating that an increase in electric field results in a proportional increase in force acting on the gas particles. The inquiry also touches on the fundamental principle that electric fields move from regions of higher potential to lower potential.

PREREQUISITES

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?
 
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
