Questions & Step-by-Step Solutions

What is the effect of introducing a dielectric material between the plates of a capacitor? (2019)
  • Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy between two plates.
  • Step 2: Know that the space between the plates is filled with air or vacuum, which allows an electric field to form when voltage is applied.
  • Step 3: Learn what a dielectric material is. A dielectric is an insulating material that can be placed between the plates of a capacitor.
  • Step 4: When a dielectric material is introduced, it reduces the electric field strength between the plates.
  • Step 5: Because the electric field is weaker, the capacitor can store more charge for the same voltage.
  • Step 6: This increase in stored charge means that the capacitance (the ability to store charge) of the capacitor increases.
