Hi,

I was trying to do a little experiment myself, and I was wondering how I can build up static charge on an metal rod.

I was wondering if I could connect a variable voltage DC power supply to a metal wire and cause static charge to build up on the wire.

I am trying to do something like, but not very similar to this:

Thanks for all the help in advance!

 

Google 'triboelectric series'

you will find a list of materials.


Two common materials at hand for most everyone, are copper and glass. On a dry day, one can rub these two materials together and seperate them quickly to leave large STATIC electric charges on them.

You and any object which they rest upon MUST be insulated from ground by dry wood, rubber, or something similar.

Read about it.
