Question
Steel is the ________ of current
- Insulator
- Conductor
- Semiconductor
- None
Hint:
A conductor allows current to flow easily through it. Insulators don't allow current to flow through it. Electric charges are absent in insulator.
The correct answer is: Conductor
- A conductor allows current to flow easily through it. Insulators don't allow current to flow through it.
- Metals conduct electricity by allowing free electrons to move between the atoms. These electrons are not associated with a single atom or covalent bond.
- So Steel is Conductor
