Approach is depending on type of electricity.
With no shape. Like unconnected wires. This easily done with particles or baked animations.
Static shape. Like lighting from sky. The best approach for this is drawing 3-4 still images and then animate them via animator. Or do same with particles and “texture animation” tab.
Dynamic shape. Thunder or lighting with dynamic point like chain lighting on top of moving objects. The best approach is to use some line renderer like vectrosity and build mesh every time, but vectrosity is bound to cpu so if you got a lot of lightings you will need gpu mesh generator. Asset store gpu lighting
If you could show an image or video with what you want, i could point you.
