Question

How do you get the part that is outlined in yellow? Wouldn't 1/C1= 1/KC1 +1/C2 give you 1/C2= 1/C1-1/KC1 when you try to solve for 1/C2 ?

A parallel-plate capacitor is filled with a dielectric whose dielectric constant is K, increasing its capacitance from C1 to KC1. A second 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. Expert Answer Asley Frye answered this 2.272 answers Was this answer helpful? Solution: Capacitance is connected in series so It is given that Cis increased to KC connected with a capacitor of capacitance C so that total capacitance is C1 So we can write C1 KC
