Light The Lamps

You certainly know that ordinary bulbs need alternating current with frequency of 50Hz for their right function. Alternating current (abbreviated AC) looks like the sinusoid - it has plus and minus voltage. This all says, that if you want to be successful in this game called Light The Lamps and light all those bulbs, you will have to always join protons (+) with electrons (-). None of them must stay alone or have two connections. Can you light all bulbs? Try it! Have fun.
