Well let's say I make a character with an electric ability. Of course you wouldn't allow creating massive thunderstorms, but would, for example, the creation of sparks be allowed? 
Or for example in a combat situation, the use of electric currents in the body to stimulate your muscles and mind, faster reaction time, etc.
Or even the use of electricity in the body to paralyze a person's muscles by touch?
Just some questions for when I make my character ^^"
