- Materials that easily allow the current to pass through it are called Good conductor
- Materials that can pass the current but not as much as good conductor are called poor conductor
- Materials that did not allow the current to pass through are called Insulator
- Current is produced when a group of electrons move through a conductor
- SI unit of Current is Ampere
- Ammeter is an instrument that measures Electric current
- SI unit of charge is Coulomb ( equal to 6 × 10 power 18 electrons )
- The electric difference between the points make electrons move
- This difference is called Potential difference
- It is measure by an instrument called Voltmeter
