Capacitors in series?
Capacitors in series have identical charges. We can explain how the capacitors end up with identical charge by following a chain reaction of events, in which the charging of each capacitor causes the charging of the next

The main purpose of having a capacitor in a circuit is to store electric charge. For intro physics you can almost think of them as a battery. . Edited by ROHAN NANDAKUMAR (SPRING 2021). Contents. 1 The Main
Why the charge is the same for capacitors connected
When the series combination is connected to the battery, it still has zero net charge because there is no path that will allow charge from the outside to flow in it. However, the conducting piece from "A" to "1" is an

6 FAQs about [Does the amount of charge in a capacitor in series change ]
What happens when capacitors are connected in series?
When capacitors are connected in series, similar but opposite charges appear on every adjacent plate. How and why this happens ? Suppose charge appeared on plate A is Q Q and then charge on plate F will be −Q − Q , as of now everything is ok but now they say charge on plate B will also be −Q − Q and so on. How can one confirm this?!
What happens when a battery is connected to a series of capacitors?
When the battery is first connected to the series of capacitors, it produces charge -q on the bottom plate of capacitor 3. That charge then repels negative charge from the top plate of capacitor 3 (leaving it with charge +q). The repelled negative charge moves to the bottom plate of capacitor 2 (giving it charge -q).
Why does capacitance decrease in a series capacitor?
The electrons that get accumulated on the top plate of the second capacitors in series has an electric field which effects the amount of charges that get deposited on the first plate. The result is less charges and hence not the complete use of the capacitors space. Thus we can say that capacitance has decreased.
Why do all capacitors have the same electrical charge?
Then, Capacitors in Series all have the same current flowing through them as iT = i1 = i2 = i3 etc. Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance. This is because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor.
Why does a series capacitor have a Q?
This occurs due to the conservation of charge in the circuit. When a charge Q in a series circuit is removed from a plate of the first capacitor (which we denote as − Q), it must be placed on a plate of the second capacitor (which we denote as + Q), and so on.
Can two capacitors in series be considered as 3 plates?
In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates.
