It is theoretically possible. And it doesnt need to be 'powerful enough'

Again, its theoretically possible.

Not due to 'electrostatic discharge'

In theory, yes. In practice stuff is normally designed so that
doesnt happen, just so it doesnt get fried by lots of other stuff.

Nope.

Its not impossible, but I doubt anyone has seen it happen.
