Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In series connection of capacitors, what is conserved physically?
A
capacitance
B
distance
C
stored charge
D
voltage
Explanation: 

Detailed explanation-1: -Capacitors in parallel have the same voltage, but different charge stored. Capacitors in series have the same charge stored, but different voltages.

Detailed explanation-2: -When capacitors are connected in series, the total capacitance is less than any one of the series capacitors’ individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.

Detailed explanation-3: -(c) When capacitors are connected in series, the magnitude of charge Q on each capacitor is the same. The charge on each capacitor will equal the charge supplied by the battery. Thus, each capacitor will have a charge of 36 C.

Detailed explanation-4: -Also for capacitors connected in series, all the series connected capacitors will have the same charging current flowing through them as iT = i1 = i2 = i3 etc. Two or more capacitors in series will always have equal amounts of coulomb charge across their plates.
