What are the rules or method to calculate the values of balancing
resistors
when using electros in series ??
Thanks Phil"Rheilly Phoull"

** Forget it - just use caps that have a large margin in excess
of the needed voltage.
Eg - two 350 volt types applied to a 500 volt supply.
The caps will very soon reach a mutual, acceptable agreement on what
precise voltage suits their individual taste !!

Electros have a fairly wide value tolerance and corresponding
leakage current variation, it's considered good practise to have
a resistor across each capacitor so that a series divider chain
is formed that swamps out the effect of leakage currents.
If not
then the individual voltages across the caps can be imbalanced
to the point where the operating voltage of one of the electros
is exceeded:
I have seen it happen and the effect does exist.

** Utter crap - if the actual max operating voltage is approached, cap
leakage current dramatically increases.
When there is a series pair of similar caps, the current flow MUST be the
same through both caps - so the one with lower leakage immediately takes
up the additional voltage. There is no problem at all as long as there is a
total voltage margin of 30 %.
I have seen it happen and the effect does exist.

With a resister correctly installed the voltage wont be problematic as
correct I refer to ARRL 1995 / filtration and bleed resistors (dualWhen there is a series pair of similar caps, the current flow MUST be the

nothing of any value noted here either , you really must learn to be
You simply ignored it.
I read it and made the right decision
Piss off.
Thanks for admiting your wrong toaster boy.
