Which of the following materials is typically used to make the connecting wires in an electric circuit because it allows electricity to pass through easily?
Options
Option A
Wood
Option B
Plastic
Option C is correct
Copper
Option D
Rubber
Explanation
Materials that allow electric current to pass through them easily are called conductors. Copper is an excellent electrical conductor and is widely used for making connecting wires. Wood, plastic, and rubber are insulators, meaning they do not allow electricity to pass through them easily, and are therefore used to cover wires or for safety components, not for conducting current.
