NCERT · Class 12 · Physics · Electrostatic Potential and CapacitanceA parallel plate capacitor has a capacitance $C$ in air. If a medium of dielectric constant $K$ is completely filled between its plates, what will be the new capacitance?
The capacitance of a parallel plate capacitor with air medium is given by: $$C = \frac{\varepsilon_0 A}{d}$$ \nWhen a dielectric medium of dielectric constant $K$ is completely introduced between the plates, the new capacitance $C'$ becomes: $$C' = \frac{K \varepsilon_0 A}{d} = KC$$ \nTherefore, the capacitance increases by a factor of $K$. Hence, the correct option is $KC$.
