Questions & Step-by-Step Solutions

What happens to the capacitance of a capacitor if a dielectric material is introduced between its plates? (2021)
  • Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy between two plates.
  • Step 2: Know that capacitance is a measure of how much charge a capacitor can store for a given voltage.
  • Step 3: Learn about dielectric materials. A dielectric is an insulating material that can be placed between the plates of a capacitor.
  • Step 4: When a dielectric is added, it affects the electric field between the plates.
  • Step 5: The dielectric reduces the electric field strength between the plates.
  • Step 6: Because the electric field is reduced, the capacitor can store more charge at the same voltage.
  • Step 7: Therefore, the capacitance of the capacitor increases when a dielectric material is introduced.
