Question

Which are the two main electrical classifications of materials based on how easily charges can move through them?
1. conductor and insulator
2. semiconductor and insulator
3. semiconductor and super conductor
4. conductor and superconductor

Answer 1

Correct Answer - Option 1 : conductor and insulator

CONCEPT:

• Conductor: An object in which charge can flow in one or more directions.
  • Materials made of metal are common electrical conductors.
• Insulator: An object in which a charge can not flow in any direction is called insulators.
• Semiconductors: The materials that have a conductivity between conductors and insulators are called semiconductors.
• A superconductor is a substance that conducts electricity without any resistance.

EXPLANATION:

• On the basis of the flow of charge, materials are Mainly classified into two groups

1. Conductors
2. Insulators

• Conductors are those through which the charge can flow. 
• Insulators are those through which charge can not flow.
• So the correct answer is option 1.
