Question

A material of very large resistance is called as:

• A. conductor
• B. semiconductor
• C. superconductor
• D. insulator

Hint:

Insulators have very high resistance and prevent the flow of electric current, unlike conductors and semiconductors.

Answer 1

The Correct Option is D

Materials are classified based on their ability to conduct electricity. The classification is as follows:
Step 1: Conductor.
Conductors, such as metals, have very low resistance and allow the free flow of electric current.
Step 2: Semiconductor.
Semiconductors, such as silicon, have moderate resistance. They can conduct electricity under certain conditions, but their conductivity can be controlled.
Step 3: Superconductor.
Superconductors are materials that, below a certain temperature, have zero electrical resistance, allowing them to conduct electricity without any loss.
Step 4: Insulator.
Insulators are materials with very high resistance that prevent the flow of electric current. Examples include rubber, glass, and plastic.
Step 5: Conclusion.
A material with very large resistance is called an insulator. The correct answer is (D).
