Cyllindrical conductor

[jreinier]

I'm trying to find the equation for an electric field at a point outside of a cyllindrical conductor. Any help would be greatly appreciated!

Assuming you are talking about an infinite conductor with a given charge per unit length, why not just use Gauss's Law to figure it out? (I guess you could always just look it up. It will take you approximately 5 seconds to Google it. But if you know Gauss's law, it's almost as fast to figure it out for yourself. And more fun.)
