Is it actually that sane to do this with big caps? That charge is going
to go somewhere, i'm assuming either as heat, or as an EMF if your
screwdriver acts as an inductor.
Am I wrong, or is thing going to do one or more of the following;
- Dump a whole lot of heat into the cap, possibly doing evil
things to the electrolyte
- Have the EMF around the screwdriver collapse, inducing current
back into the cap
- Somehow dump the energy as heat into the screwdriver if there
are reasonable RC losses
I'm wondering mainly about *really* huge caps, and how to deal with them
safely. I'm thinking some sort of actual load across them rather than
just shorting them maybe?
