Conductors and insulators
Conductors and insulators
| Type | Does it let charge pass? | Examples |
|---|---|---|
| Conductors | Yes, easily | Copper, aluminium, salt water |
| Insulators | No; charge stays where it is | Plastic, glass, dry wood, rubber |
- This is why electric wires are covered with plastic
- and why screwdriver handles are made of an insulating material.
