(amperage:Current flow, or electron flow, is measured in
amperes. While we normally consider that one ampere is a rather small
current of electricity (approximately what a 100-watt light
bulb would draw), it is actually a tremendous flow of
electrons. More than 6 billion electrons a second are required to
make up one ampere)
