MCQ
Name the material used for making the connection wires:
- ATin
- BCopper
- CLead
- DTungsten
✓
Answer
- Copper
Explanation:
Copper is a good conductor of electricity as it allows the electricity to flow through it easily.
Copper as a connecting wire has very low electrical resistance.
Copper combines several properties that have traditionally made it preferred for most electrical wiring.
It provides good contact surface, is ductile (is easily bent repeatedly without breaking) and it is not very expensive and is easy to manufacture.
