That wasn't a formula, Max. Okay, leave the "power" out of it. Current and amps are interchangeable. Anyway, you're sober, I'm not.
Amps kill, voltage doesn't, except in rare occasions, like the stories that you hear when a person is tazed and dies. Tazers are high voltage, low amperage. The high voltage messes with your muscle control and nerves, but one usually lives.
