Electron Mean Free Path in air & Electric field requirements?

Click For Summary
SUMMARY

The discussion focuses on calculating the mean free path of a free electron in air under the influence of an electric field. Key parameters include the electric field strength and the distance between plates necessary to impart an energy of 80 eV to the electron. The calculations are based on standard atmospheric pressure (1 ATM) conditions. The participants emphasize the importance of understanding the relationship between electric field strength and energy transfer in this context.

PREREQUISITES
  • Understanding of mean free path calculations in gases
  • Familiarity with electric field concepts and equations
  • Knowledge of energy transfer mechanisms for charged particles
  • Basic principles of gas behavior at standard temperature and pressure (STP)
NEXT STEPS
  • Research the formula for calculating mean free path in gases
  • Learn about the relationship between electric field strength and energy imparted to charged particles
  • Explore the effects of atmospheric pressure on electron behavior in air
  • Study the principles of electron acceleration in electric fields
USEFUL FOR

Physicists, electrical engineers, and students studying plasma physics or gas dynamics will benefit from this discussion.

I can't seem to understand the math. If I have a free electron in air, surrounded by an electric field, how do I determine and calculate the mean free path, the electric field strength, and the distance between plates required to impart an energy of 80 eV to the free electron?

Are you talking about 1 ATM (STP) or something less?
