A parallel-plate capacitor with plate area \( A \) has separation \( d \) between the plates. Two dielectric slabs of dielectric constant \( K_1 \) and \( K_2 \) of same area \( \dfrac{A}{2} \) and thickness \( \dfrac{d}{2} \) are inserted in the space between the plates. The capacitance of the capacitor will be given by:
