My first troller

There aren't any guides because Electric is the newest control set and nobody has gotten around to writing one yet. Cold is the newest secondary, too.

Electric Control is probably the second lowest damage control set there is. The only one lower is Ice Control. If you want to do damage as a controller, the better choices are Fire (AoE Melee), Plant (AoE cone/ranged), Illusion (ranged single target with pets), Mind (ranged single target damage, good AoE control in later levels) and Gravity (good but slow single target damage, unique playstyle due to level 26 power and pet). Earth Control is also low damage, but slightly higher than Electric.

Your powerset combo is definitely a support character -- plan to team rather than solo. You can solo some as you get into the upper levels, once you get your pets at 32 and the Resistance Debuffs from Sleet at 35 and Heat Loss at 38, and then the APP powers in the 40's, but it will always be lower damage and slower to solo than most other controllers. (If you want to try to solo, take Electric Fence slotted for damage and consider adding Air Superiority.)

Leveling up, you will want to focus on your AoE sleep (Static Field) and endurance drain. Jolting Chain provides a good short-term distraction to give you time to fire off other powers and drain a little bit more endurance. Chain Fences lets you keep foes in the area without preventing knockdown. The confuse power, Synaptic Overload, is a really nice opening attack since it does not draw aggro.
