Four capacitors are connected in series with a battery, as in the figure below, where C1 = 3.24 湩, C2 = 6.11 湩, C3 = 12.1 湩, C4 = 25.0 湩, V = 18.4 V.

(a) Calculate the capacitance of the equivalent capacitor.
湩

(b) Compute the charge on C3.
湣

(c) Find the voltage drop across C3.
V

C4 is removed from the circuit, leaving only three capacitors in series.
(a) Find the equivalent capacitance.
Ceq = 湩

(b) Find the charge on C2.
Q = 湣

(c) Find the voltage drop across C2.
ΔV = V
