Is electricity weightless?

Question

The understanding is that electricity simply *passes* through a conductor pushing electrons but isn’t mass required to be able to “push”?? And while at it I wonder… Is there evidence of electricity being present in other planets? or in open space? Please ELI5

Answer 1

Electricity is electrons moving around, so yes, there’s mass passing through a conductor. But free-moving electrons make up less than 0.01% of a conductor, so it’s barely noticeable.

There’s of course electricity on other planets, e.g. lightning flashes have been recorded in Saturn’s atmosphere.
