Stuck Charge, Moving Charge (Physics Level 8)
Show notes
We're hunting for the one difference between those two. First we'll make charge pile up and stay put, then we'll let it go and count it as it moves, and by the end you'll know exactly what an amp is counting.
The spark and the glow differ in one thing only: whether the charge keeps moving. A zap is a pile that empties all at once. A light is charge passing steadily, and amps are just the count of how much gets by each second, which is why the counter has to stand in its way.
