- Circuit
- A closed path that allows electric current to flow from a power source through a conductor and back
- Closed circuit
- A circuit where the path is complete and allows electric current to flow
- Open circuit
- A circuit where the path is broken or incomplete, stopping the flow of electric current
- Conductor
- A material that allows electric current to flow through it easily
- Insulator
- A material that does not allow electric current to flow through it easily
- Resistance
- The opposition or difficulty that a material presents to the flow of electric current
- Electric current
- The flow of electric charge through a conductor
- Voltage
- The electrical force or pressure that pushes electric charges through a circuit
- Volt
- The unit used to measure voltage
- Ampere
- The unit used to measure electric current
- Ohm
- The unit used to measure electrical resistance
- Power
- The rate at which electrical energy is used or transferred
- Watt
