In a house, a single incoming wire at high potential relative to ground supplies electric power to the building. How are the appliances typically connected between this wire and the ground?

1. Every appliance in the house needs to operate at the same rated mains voltage. 2. A parallel connection puts both ends of every appliance across the same two points, the high-potential wire and ground. 3. Being tied across the same two points, every appliance in a parallel arrangement receives the same voltage difference. 4. A series connection would instead force the same current through every appliance and split the voltage unevenly between them, which is not how household wiring works. 5. So household appliances are connected in parallel, giving each the same voltage difference. _Source: OpenStax Physics (CC BY 4.0), Ch 19 "Electrical Circuits", section 19.3 Parallel Circuits_
