Question

Two identical parallel plate capacitors are placed in series and connected to a constant voltage source of V volt. If one of the capacitors is completely immersed in a liquid of dielectric constant K , then the potential difference between the plates of the other capacitor will change to, K K + 1 V, K + 1 K, 2 K K + 1 V, K + 1 2 K V

In series combination, charge is same. V ∝ 1 C Now, V 2 V 1 = K C C = K 1 But V 1 + V 2 = V or V 2 K + V 2 = V o r V 2 = K K + 1 V
