A capacitor of capacitance C1 = 1.0 μF withstands the maximum voltage V1 = 6.0 kV while a capacitor of capacitance C2 = 2.0 μF, the maximum voltage V2 = 4.0 kV. What voltage will the system of these two capacitors withstand if they are connected in series?

Best answer

Amount of charge, that the capacitor of capacitance C1 can withstand, q1 = C1 V1 and similarly the charge, that the capacitor of capacitance C2 can withstand, q1 = C2 V2 . But in series combination, charge on both the capacitors will be same, so, qmax, that the combination can withstand = C1V1,

as C1V2 < C2V2 , from the numerical data, given. 

Now, net capacitance of the system,
