Hi Engr,

It can't be calculate that way you have take the whole complete circuit into consideration and this can only be understood by the designer.

I suggest that you visit this website:

http://www.electronicrepairguide.com/series-and-parallel-capacitors.html

for capacitor connected in series and parallel. There must be reason it use the non polar cap. Anyway you can try that and see how it goes since you can't find original value. I suggest that you use non polar cap instead of cap with polarity.

Can i improverse and connect two polarized of 10uf by 50v back to back
i.e + to + then connect the other pins to the board.

i removed the spoiled one from an old monitor cct.

Thanks Justine i have been following your articles closely

I have googled my way here. It will be of great help to me if you please guide me to replace a non-polorized capacitor with a electrolytic capacitors in one of my 230V 50 Hz AC driven Simple 15-20 LED Lamp. I am using a Cap. reactance to limit current. I already got it working with non-polorized cap. 474J 250V(.47 uF or 470nF), but my requirement is a higher volt rating (>400 or 600), which I am unable to lay my hands on. So what value polorized cap connected back to back will do the trick safely. How do we find these these values because, next I am going to need, a substitute for .22 uF >400V.

Thanks is advance

The best is to use back the same type of capacitor as certain circuit can't run on different type of capacitor. Capacitors are quite easy to get from the market. Try visit this link:

How do I replace the electrolytic capacitors with a non-polorized capacitor on my tube receiver? Which side goes to the positive and which side goes to the negative?

Thanks and hoping to hear from you soon.
