Question
Water is the ______ of current.
- Conductor
- Insulator
- Semiconductor
- None
Hint:
A conductor allows current to flow easily through it. Insulators don't allow current to flow through it and When the salts or impurities are added to pure water, they form electrically charged ions and hence make the conductance possible.
The correct answer is: Conductor
- 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.
- When the salts or impurities are added to pure water, they form electrically charged ions and hence make the conductance possible. The presence of ions is the reason why tap water or impure water conducts electricity whereas the pure water doesn't conduct electricity.
