- Voltage has a small consideration since this is what disrupts
- your nervouse system, but current is the main consideration. The
- shockers some people carry have a high voltage ( 120,000 & > ), but they
- are only powered by a nine volt battery so the current is very low. And
- a 1.5 volt battery is enough to stop your heart if the resistance is low
- enough ( I've been told bridgeing it between open cuts on the thumbs could
- give a low enough resistance). Remeber that voltage=current*resistance.
- These must equal out.
- Well, thats my 2 cents worth.
