Electricity is not affected by Gravity, short of a black hole. Unless Gravattack was willing to destroy the Earth along with himself and Thor, the electricity would search for the fastest way to 'ground' -which I'm guessing in this situation Gravattack would be the closest ground.

That being said, Gravattack is a planet and therefore almost certainly immune to electrical attacks.
