It is not an average. It is a rate. If the measure will be shorter than one second, then another unit of measure should be used.

Like I said. There are better terms to use to describe the same event. You are obviously not new to being the complete asswipe that you are.

If a capacitor stores a coulomb of charge, and you remove it all, you get a coulomb, one ampere-second, out, and it doesn't matter how long you take to do it, or whether ths discharge is constant, exponential, quarter-sine, or anything else. You can get one constant ampere for one second. Or get 0.1 amp for 10 seconds. Or a thousand amps for a millisecond, if it's a suitable good cap. It's like a gallon jug that contains one gallon of water: whether you empty is fast or slow, uniformly or not, you always get a gallon in the end. That's how much is in there! John |
