The function of a dielectric in a capacitor is
- A to reduce the effective potential on plates.
- B to increase the effective potential on plates.
- C to decrease the capacity of capacitance.
- D to reduce the plate area of the capacitor.
Answer & Solution
Correct Answer
(A) to reduce the effective potential on plates.
Step-by-step Solution
Detailed explanation
The function of a dielectric in a capacitor is to increase the capacitance. This is achieved by reducing the electric field between the plates, which in turn reduces the potential difference across the plates for a given charge. Therefore, the correct option is to reduce the effective potential on plates.
