Working
This total is always smaller than the smallest single capacitor.
Capacitors in series or parallel, or one of the formulas: charge, stored energy, reactance, or the RC time constant.
Add as many capacitors as you need, or fill in the formula's known quantities, each in the unit you have.
The total or the unknown quantity in convenient units, with the working.
The opposite way to resistors: in parallel they simply add (C = Cโ + Cโ + โฆ), and in series their reciprocals add (1/C = 1/Cโ + 1/Cโ + โฆ).
E = ยฝCVยฒ. A 1,000 ยตF capacitor charged to 25 V stores about 0.31 J.
ฯ = R ร C, the time to charge to about 63.2% of the supply voltage (or discharge to 36.8%). After 5ฯ it's over 99% charged.
