Dielectrics

The function of a dielectric in a capacitor is

Show answer and solution

Answer: (a)

Induced charges on the dielectric reduce the field between the plates to $\frac{E_0}{K}$ .
For the same charge the potential falls to $\frac{V_0}{K}$ , so $C$ increases $K$ times.
So the answer is (a) to reduce the effective potential on plates.
