Hallo all,
Just a quick question,Have been reading a lot, first time posting. If I need a capacitor with the value of said a 100v DC, can I perhaps connect two 50V DC caps in series to get the same 100V value.
Thanks

100V is not a capacitor value but a rating. You can connect caps in series, but the capacitor value reduces and you need balancing resistors. Two 50uF 50V in series make a 25uF 100V cap. Generally not worth doing unless you need really high voltages.
What DF96 said.
Caps work "opposite" of resistors - they add in parallel and divide in series.
SO two same value caps in series will result in a total half of one of them.
We do this mainly in high voltage power supply filters. We might need a 500v or greater cap, and they are not readily available from suppliers. So we put a couple 350v caps in series. Comon enough in guitar amps, anyway.
