I can see Ruby having the heat resistance thing ya.

as for the power to generate electricity, I think that is a Sapphire ability. She is shown to be able to move at intense speeds during Jail Break, and Lightning is often associated with speed in games and TV shows. So it could be that she is capable of generating lightning, and thats why she has the energy to move so quick.
