HI, please do not get me wrong, I am trying to grasp and learn when HV capacitors get dangerous and I am confused right now. Your help is extremely appreciated. Caps discharge their energy very very quickly and said THERFORE to be dangerous, but a Van de graaf also discharge its energy very very quickly. For instance in theory to illustrate( my point):
1- fully charged 100kv 25pF capacitor discharge is 250amp in 100 millionth of a second( 0.125J).
2- fully charged 100kv 25pF V.D.G discharge is 250amp in 100 millionth of a second. (0.125J)
So both have the same charge and capacitance, why is then a capacitor always said to be very dangerous? A VDG is a capacitor and also will discharge its entire charge in a very very short time?
To make my point as clear as possible:
Are fully charged 100kv 25pF VDG and a 100kv 25pF Capacitor equally "dangerous" to human touch? (they should be?)
Thanks
Best regards
