6. Seven capacitors are connected between points a and b, as shown in the figure on the right, with C1 = 4.00 µF, C2 = 6.00 µF, C3 = 5.00 µF, and C4 = 3.00 µF. C2 C2 a) What is the equivalent capacitance between points a and b? b) If the potential difference between a and b is 60.0 V, what is the charge on the capacitor C3? c) We now insert a dielectric with K = 3.20 into both of the C4 capacitors. What is the new equivalent capacitance between points a and b?
