Correct Answer - Option 1 : conductor and insulator


  • 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.
  • superconductor is a substance that conducts electricity without any resistance.


  • 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.
