Hi Tina,
I read your mail and think about ... the voltages divide evenly... If you
put 2 capacitors 100 pF and 1 nF in series and proposed you have ideal good
capacitors then the total voltage of esp. 10 kV divides to 1 V over the 1 nF
Capacitor and the rest (10 kV- 1 V) over the 100 pF Capacitor. Is that what
you mean?
