Fully discharge a metal plate?

Click For Summary

Discussion Overview

The discussion centers around the question of whether it is possible to fully neutralize a charged metal plate. Participants explore various methods and considerations related to charge neutralization, including the effects of capacitance and environmental factors.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants propose that connecting the charged metal plate to a metal body with a relatively large capacitance will reduce its charge to a negligible level, but not eliminate it entirely.
  • Others suggest that high humidity in the air may facilitate the discharge of static charge to the environment and ground.
  • A participant questions whether repeating the process of connecting to a large capacitance could lead to a high probability of the charge being less than that of a single electron.
  • Another participant emphasizes the importance of defining how the charge will be measured before discussing neutralization methods.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of various methods for fully neutralizing a charged metal plate, and no consensus is reached regarding a definitive solution.

Contextual Notes

The discussion includes assumptions about the nature of charge measurement and the conditions under which neutralization is considered complete, which remain unresolved.

is there any way to fully neutralize a charged metal plate ?
connecting it to metal body of relatively huge capacitance will make its charge negligible but not zero?
is there any other way?

High humidity in the air will help to discharge any static charge to the environment and ground...

Perhaps repeat the process until there is a high probability of the charge being less that that of a single electron?

I think you first need to define how you will measure the charge.
