No silly, only STH/BLM does that.
You don't get force lightning as a jedi. Instead you might be able to get Emerald Lightning; Plo Koon and Luke could do this. I believe that Jacen Solo did it once before he turned into a sith. Instead of destroying matter with electricity you develop a current between you and the target that destroys the force that binds them together by draining it back into you.
It's much, much cooler than standard force lightning.
