How to safely create static electricity from AC current

Click For Summary

Discussion Overview

The discussion centers around methods to generate static electricity from an AC outlet, specifically for the purpose of creating an effect where hair stands on end. Participants explore various approaches, including the use of electrostatic generators and alternative methods.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about simple methods to create static electricity from an AC outlet for an experiment.
  • Another suggests that a portable Van de Graaff generator might be necessary, questioning if it is the only option available.
  • A third participant humorously proposes rubbing hair with a balloon as a simple method to generate static electricity.
  • Discussion includes a classification of electrostatic generators into friction machines and influence machines, highlighting the triboelectric effect and electrostatic induction.
  • A participant mentions the Kelvin Water Dropper as an interesting electrostatic generator that does not require AC power, noting its popularity at a museum.
  • Another participant expresses interest in building a Kelvin Water Dropper, suggesting it could be effective in areas with frequent rain.
  • A recommendation is made to use Bill Beaty's website as a guide for constructing a Kelvin Water Dropper.

Areas of Agreement / Disagreement

Participants present multiple methods and ideas without reaching a consensus on the best approach to generate static electricity from an AC outlet. Various viewpoints and suggestions remain contested.

Contextual Notes

Some methods discussed depend on specific conditions, such as the availability of materials or environmental factors like rainfall for the Kelvin Water Dropper. The effectiveness of different approaches may vary based on these factors.

Is there a simple way to "make" static electricity from an AC outlet? Looking for a way to make my hair stand (what is left of it) on its end for an experiment. Thanks for your comments in advance.

I guess I need a portable Van de Graaff generator - is that the only way?

Welcome to the PF.

Rub your hair with a balloon?
 
besides that
 
Electrostatic generators can be divided into two categories depending on how the charge is generated:

1. Friction machines use the triboelectric effect (electricity generated by contact or friction)

2. Influence machines use electrostatic induction

The favorite electrostatic generator at our Museum of Arts and Sciences is the “Kelvin Water Dropper”. All of our visitors love it. It does not need AC power; only falling water powers it!

BobbyWhy - thanks I have never heard of the KWD! -- Seems like it would be cool to build on a down spout where it rains a lot...
 
Windadct, If you intend to build a Kelvin Water Drop Electrostatic Generator, I highly recommend using Bill Beaty's website for you guide. See:
