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.

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).
Why capacitor connected in parallel in circuit?
Any answer "why" will depend on the rest of the circuit, which may an electric motor, a filter, or any number of other applications.If you're asking about 2 or capacitors in parallel, it is to provide a higher capacitance, since the total C will be the sum of each device's individual capacitances.Ctotal = C1 + C2 + C3 ...+ CnConversely capacitors in series obey the reciprocal law:1/Ctotal = 1/C1 + 1/C2 + 1/C3 ...+ 1/Cn
What is the effect on the circuit if we add a capactior in parallel with another capacitor?
Capacitors in parallel simply add up, similar to resistors in series... CTOTAL = sumI=1-N (CI) Capacitors in series work like resistors in parallel... CTOTAL = 1 / sumI=1-N (1 / CI)
When two capacitors connected with resistance in series?
(r+(c/2))
How capacitors are arranged?
Capacitors are one of the standard components in electronic circuits. Moreover, complicated combinations of capacitors often occur in practical circuits. It is, therefore, useful to have a set of rules for finding the equivalent capacitance of some general arrangement of capacitors. It turns out that we can always find the equivalent capacitance by repeated application oftwosimple rules. These rules related to capacitors connected in series and in parallel.

A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
Why capacitors are almost always connected in parallel and not in series?
to provide a discharge path for voltages.
Why capacitors are not connected in series in power line?
capacitor's characteristic is charging and discharging. discharged energy will be dropped by load . so it is connected in parallel
Two capacitors of 2µF are connected in parallel A 1 µF capacitor is added in series What is the combined capacitance?
For capacitors connected in parallel the total capacitance is the sum of all the individual capacitances. The total capacitance of the circuit may by calculated using the formula: where all capacitances are in the same units.

In series and parallel capacitance?
When capacitors are connected in series, the totalcapacitance 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. As we've just seen, an increase in plate spacing, with all other factors unchanged, results in decreased capacitance.Thus, the total capacitance is less than any one of the individual capacitors' capacitances. The formula for calculating the series total capacitance is the same form as for calculating parallel resistances:When capacitors are connected in parallel, the totalcapacitance is the sum of the individual capacitors' capacitances. If two or more capacitors are connected inparallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. As we've just seen, an increase inplate area, with all other factors unchanged, results inincreased capacitance.Thus, the total capacitance is more than any one of the individual capacitors' capacitances. The formula for calculating the parallel total capacitance is the same form as for calculating series resistances:As you will no doubt notice, this is exactly opposite of the phenomenon exhibited by resistors. With resistors, seriesconnections result in additive values while parallel connections result in diminished values. With capacitors, its the reverse: parallel connections result in additive values while series connections result in diminished values.REVIEW:Capacitances diminish in series.Capacitances add in parallel.
Why you use capacitors in lines?
Capacitors are connected in series with some lines (series compensated lines) and in parallel. Capacitors in parallel are used to prop up the voltage at that location by injecting reactive power onto the grid. Capacitors in series are used to cancel out some of the inductance of the line, which allows for more power to be transported through the line. Capacitors at load centers are often used for power factor correction, and are connected in parallel (line to ground). To achieve efficiency in a power delivery system it is most efficient to have the current and voltage in phase. Often the load is inductive hence the current lags the voltage (due to motors etc.). Capacitors are switched in and out of the transmission system to counteract this effect.
Why the charge is not equal if you connect the capacitors on parallel?
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors' capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors. As we've just seen, an increase in plate area, with all other factors unchanged, results in increased capacitance.The total capacitance is more than any one of the individual capacitors' capacitances.The equivalent capacitance of two or more capacitors connected in parallel is simply the sum of the individual capacitances.

Capacitors in parallel simply add up, similar to resistors in series... CTOTAL = sumI=1-N (CI) Capacitors in series work like resistors in parallel... CTOTAL = 1 / sumI=1-N (1 / CI)
