A parallel-plate capacitor is filled with a dielectric whose dielectric constant is K, increasing its capacitance from C1 to KC1. Asecond capacitor with capacitance C2 is then connected in series with the first, reducing the net capacitance back to C1. Part A What is the capacitance C2 of the second capacitor? Express your answer in terms of K, C1, and constants. ΑΦ ? C2 =
