How fast can Capacitors charge and discharge and whats the Math Formulas?
You are limited by the internal resistance of the capacitor for charge time. But the minimum charge time for a large electrolytic is probably in the 10-100ms range. For smaller caps, it is in the µs or ns range. Again, for discharge, the only limit is the internal resistance of the cap, sometimes called ESR, plus of course your external circuit. And by how many caps you have in parallel and the value of the caps. It can easily be hundreds or even thousands of amps. current = voltage on cap / ESR (plus any external resistance) Discharge times can be in the mS range or even lower with proper design, with low ESR values, and low inductance in the connections. .
