Question: What happens to the capacitance of a capacitor if a dielectric material is inserted? (2021)

Options:

  1. It increases
  2. It decreases
  3. It remains the same
  4. It becomes zero

Correct Answer: It increases

Exam Year: 2021

Solution: 

Inserting a dielectric material between the plates of a capacitor increases its capacitance due to the material\'s ability to reduce the electric field.

Questions & Step-by-Step Solutions

What happens to the capacitance of a capacitor if a dielectric material is inserted? (2021)
  • Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
  • Step 2: Know that a capacitor has two plates and a space between them, which can be empty or filled with a material.
  • 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 inserted, 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.
  • Step 7: More charge stored means higher capacitance.
  • Step 8: Therefore, inserting a dielectric increases the capacitance of the capacitor.
