Electric circuit formula is (W/V)20%+.
how many watt needs to run that equipment like 1500W
how many voltage that u can get from your electic company like 220V
than (1500/220)20%+=8.18 So u need 8 to 10 ampere circuit for this equipment.
ALL computers are no more than logic circuits linked together :)
Of course OP is massively confused in his use of the term "electric circuits" when meaning "logic circuits", which might have hurt his attempts at using a search engine (itself a logic engine, ironically) to find the information he is looking for.
