Electrical Engineering MCQ on Basic Concepts

Conductors are defined as materials that:

  1. Do not conduct electrical current under normal conditions
  2. Easily conduct electrical current
  3. Have electrical conduction properties in between conductors and insulators
  4. None of above

Correct answer: 2. Easily conduct electrical current

Explanation:

  • Conductors are the materials that possess electrical conduction ability
  • Metals are good conductors of electricity
  • Among conductors, the best ones are single-element materials
  • Examples of good conductors include: Copper (Cu), Silver (Ag), Gold (Au), and aluminium (Al)
  • Good conductors are characterized by atoms with only one valence electron
  • In good electric conductors the valence electrons are very loosely bound to the atom. These loosely bound valence electrons become free electrons.
  • In a conductive material the free electrons are valence electrons.
