- Electrical Systems
- A system is a collection of parts that work together to do a particular function
- The three stages of an electrical system are: Input, Process, Output
- A conductor allows electricity to flow through it
- Copper
- An insulator prevents electricity from flowing through it
- PVC
- A resistor can reduce the current flowing through a circuit to protect delicate components
- Voltage pushes the current around a circuit
- Input devices: switches, LDRs, thermistors
- Output devices: bulbs, motors, buzzers
