Why Doesn't a 1.5V Battery Shock You?

[seang]

What are the biggest outlets around? There's a 600V in our school's lab.

Easier than you expect

That's kinda stupid. A 100 pF capacitor would have to be charged to a million volts to store 50 J. Good luck finding such a capacitor.

Not that I'm looking for it ,but a 5 feet diameter smooth metal ball elevated 5 feet above ground plane is kinda construction plan for such a capacitor.:rofl:
For starter,not very complicated I think .
BTW,see the link above I found about giant Van de Graaf in Boston ( ~8' spheroids)!
