calculating combination circuits for capacitance

[krayvonk]

say I have 2 capacitors in parallel, connecting to another capacitor in series.

If you compute parallel first, its a completely different result from computing series for each then adding them together.

which way is correct?

Do the caps in parallel first.

You can only use the series formula if there is nothing connected in the middle, so you have no choice but to first replace the two parallel caps by their equivalent value and then connect it in series with the third one.
