The first is voltage which stands for the force of electricity. And then we have amperage, which has to do with the flow or the current of the electricity. And if you take that force or voltage and multiply it against the current or amperage, you end up with the term, that's probably most important to you as a server administrator, which is wattage which is the actual measurement of electrical usage.…
