Hi

Can anyone explain me how to calculate the current between two objects which

has a high voltage field between them?

Let's say you have an object with area A cm^2 located L cm from an object

with inf. size (ground), and there is a voltage of V volt between them. The

objects is located in air. Is it possible to calculate the current flowing

in the field from 0volt until you get a spark?

I have tried to search the web, but I am not able to find an easy

explanation of how this relation is.

The reason I'm asking is that I'm writing control software for controlling

the high voltage field between an electrostatic spray painting gun and the

object painted. So I'm really just an software guy trying to understand the

high voltage process. Any info would be great.

Thanks.

Morten
