Hello Gents,

Quick question, you have a circuit with a Vs of 120Vrms (170pkpk). If the complete circuit consists of the voltage source and two caps in series would you be able to use 100V rated caps? I am trying to find out if the voltage limit of series caps is double/halved etc. Also if the same applies to caps in parallel.

Thanks,
Tony D.

 

Caps in series add their voltage ratings but you have to allow for leakage currents by adding shunt resistors to make sure they share the voltage equally. But then you lose the absolute isolation factor, if that matters in that particular circuit.

Caps in parallel do not add their voltage ratings, and this site does not allow circuits that are connected directly to the wall outlet. I'll expect the moderators to swarm on this quickly.

 

Swarm is harsh, but I guess it will do. I am closing this thread as it violates AAC policy and/or safety issues.
