Study Notes
Practical Wiring
- Current flows in closed loops.
- Parallel circuits allow each device to be controlled by its own switch.
- When one appliance is turned on, only that appliance operates; others remain off.
- All appliances on a parallel circuit draw current from the same source.
- If too much current passes through a conductor, it can overheat.
- Homes typically have multiple parallel circuits to prevent overheating and limit current demands on the supplying wires.
- Large cables are needed to supply the complete total current required by the house, compared to smaller wires used for individual devices.
