Question
____________ is the insulator of the current.
- Steel
- Iron
- Copper
- Rubber
Hint:
- All Metals are Conductors and Insulators don't have free electrons
The correct answer is: Rubber
- A conductor allows current to flow easily through it. Insulators don't allow current to flow through it. Electric charges are absent in insulator. Conductors are used in making electrical equipment.
- All Metals are Conductors
- Here In above options only rubber is the appropriate answer because it is not metal and it has no free electrons
