Calculating Radius of electric field

Click For Summary
SUMMARY

The calculation of the radius of an electric field is influenced by multiple variables, including the shape of the object, vacuum state, voltage, and amperage. While the electric field theoretically extends infinitely, its practical influence diminishes with distance, leading to the need for experimental derivation to determine effective ranges. The discussion emphasizes that physicists utilize established principles to quantify these variables, allowing for a more precise understanding of electric field behavior in practical applications.

PREREQUISITES
  • Understanding of electric field theory
  • Familiarity with voltage and amperage concepts
  • Knowledge of experimental physics methods
  • Basic principles of electromagnetism

Question: Is there a way to calculate the radius of an electric field? By that I mean, say we have a cathode on one side, how far away can the anode be? Is there a way to calculate this? I'd imagine it would need to be experimentally derived due to the number of variables (shape of object, vacuum state, voltage, amperage, etc) but physicists know a *bit* more about this than I do!

Thanks again for all the assistance, and I hope I put this in the correct topic-

The electric field in theory never vanishes no matter how far you are from it, so it depends on how weak it would have to be for you cut it off and just think of it as zero.
