Capacitors are said to be connected together "in series" when they are effectively "daisy chained" together in a single line. The charging current ( iC ) flowing through the capacitors is THE SAME for all capacitors as it only has one path to follow.
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. Therefore, capacitors connected together in series must have the same charge.
QT = Q1 = Q2 = Q3 , etc.

What is the principle of operation of gang capacitors?
Gang capacitors are a series of capacitors that are mounted to a common location. When they are mounted in series, they can be controlled by a single switch instead of multiple ones.
When capacitors ate connected in series the capacitance increase or decrease?
Capacitors in connected in series result in a higher voltage rating, but lower capacitance. Two 470uF 50V capacitors connected in series will give you a total of 235uF, but you can put up to 100V across the series combination. Two 470uF 50V capacitors connected in parallel will give you a total of 940uF, across which you can put 50V (the voltage rating does not change for capacitors in parallel).
When two capacitors connected with resistance in series?
(r+(c/2))
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
If two capacitors of capacitance 22 microfarads and 45 microfarads are connected in series what will be the equivalant capacitance?
Capacitors in series are like resistors in parallel.CSERIES = C1 C2 / ( C1 + C2 )Plug 22 and 45 into that equation and you get about 15 microfarads.

Capacitors block......... frequencies filling the blank?
It depends on whether the capacitor is series or shunt. If series, capacitors block low frequencies. If shunt, capacitors block high frequencies.

What is the relationship between capacitors in series and resistors in series?
resistor isdefined as the opposing the current flow in a circuit. capacitor is defined as the store the electric field in one forth of the cycle and the another quarter cycle stored energy will be released

How voltage doubler works?
The voltage doubler works by charging alternate capacitors on alternate half-cycles. Since the capacitors are in series, the voltage doubles.
What happens to capacitors that are connected in series?
The total capacitance from capacitors that are connected in series are added up inversely; 1/Ctotal = 1/C1 + 1/C2 + ... + 1/Cn, where Cn is the capacitance of the nth capacitor.
What would happen if more capacitors were added to a series circuit already containing two capacitors?
A: For one thing the total capacitance will decrease . If the voltage rating are different then more problem will become evident. That is if they are added in series.
Why capacitor used in transmission line?
Capacitors can be used to decrease the inductance of power lines (series compensation), and for voltage support (capacitors are put in parallel with the system).
What voltage must be applied to fully charge capacitors in series?
To fully charge capacitors in series, you would want to make sure they are all rated for the same voltage, and then apply the sum total of the rated voltage (if they are 25 volt caps, and you have three, then apply 75 volts). It may be worth noting here that this really is an academic exercise, since putting capacitors in series results in lower capacitance. Most often capacitors will be paralleled so a higher capacitance is attained.
Can you double the volts by connecting two capacitors?
Two capacitors can be connected in series to double the voltage rating, but they must be identical capacitors and they should each have a resistor in parallel to equalise the voltages, the resistors chosen to pass about 1 mA. With two capacitors in series the overall capacitance is half the capacitance of either capacitor. The combination stores equal charge at double the voltage and the stored energy is doubled.
