That makes life more enjoyable. Are you ever amused? Certainly not
here.

I said that film caps do not use single-atom thick metalization, and
that some use combined aluminum and zinc metalization. I learned those
in a few minutes of web searching.

It wasn't hard to find facts about metalization. The mystery is why
you couldn't.

I wonder how really big caps are constructed, like the utility
power-factor things.

I used to buy huge oil caps when I was a kid, to pop flashtubes or
just make loud noises. I'd run them at all the voltage I could make,
like 25 KV.
