Which of the following statements about dielectrics is true?.
- A.Dielectrics increase the potential difference across the capacitor
- B.Dielectrics decrease the charge stored in the capacitor
- C.Dielectrics increase the capacitance of the capacitor
- D.Dielectrics have no effect on capacitance
Model answer
What a good answer should say
- Dielectrics increase the capacitance of the capacitor
Explanation
Why this works
Dielectrics are materials that, when placed between the plates of a capacitor, increase its capacitance by reducing the electric field strength, allowing more charge to be stored.
