MHT CET 2025 Physics question
Two parallel plate air capacitors of same capacity 'C' are connected in parallel to a battery of e.m.f. 'E'. Then one of the capacitors is completely filled with dielectric material of constant 'K'. The change in the effective capacity of the parallel combination is
Answer: (D)
Solution
Initially, the parallel combination has . After one capacitor is filled with the dielectric its capacity becomes , so . The change is
