Questions & Step-by-Step Solutions

Which of the following materials is commonly used as a dielectric in capacitors? (2023)
  • Step 1: Understand what a dielectric is. A dielectric is a material that does not conduct electricity and can store electrical energy.
  • Step 2: Know that capacitors are devices that store electrical energy using dielectrics.
  • Step 3: Learn that common dielectric materials include glass, plastic, ceramic, and air.
  • Step 4: Identify that glass is often used because it has a high dielectric constant, which means it can store more energy.
  • Step 5: Conclude that glass is a commonly used dielectric material in capacitors.
