@winny: Same as anywhere else: \$ ... \$ for inline, $$ ... $$ for block. It's kind of weird that that works, but simple HTML entities (e.g., ±) does not.

| Oct 25, 2022 at 12:04 | comment | added | brhans | You have to supply charge to the capacitor in order for it to store energy in an electric field. You can't use an electric field to charge a capacitor unless you can get the field to make some charge flow into the capacitor, and flowing charge is current, so ... | |
