I got like 10.5u. How did you do voltransistor?

12uF sounds better

I used two ac sources with the same frequency and the same voltages. One I changed the dc to ac for the circuit he has posted and the other I added to one capacitor. They are both highlighted so the amperages are measured. I changed the single capacitor value to match the same amperage as the main circuit he has posted. Which is very close to 12u.

place default AC source 1V 1kHz and measure the current 75.2mA. Than calc Xc=1/75.2mA=13.263Ohm than calc C=1/(2*pi*f*Xc)=1/(6.283*1kHz*13.263Ohm)=12uF! Voila. Volte is very pragmatic, great!

Thankyou, hurz. You are smart. Satur0sz is going to be happy. Lol.

Ok, yes you would probably get the best answer that way. I tried to calculate it from the given values but im not very sure i did it the right way;)
