Can a capacitor increase the voltage?
Capacitors are used to store charges and capacitors alone cannot increase the voltage. Capacitors are connected along with diodes to form the voltage multiplier circuit. Capacitors can be used in many circuits where the output voltage has to be more than the input voltage.
How to increase the working voltage of two capacitors?
To increase the working voltage of two capacitors, connect them in series. For example, two capacitors C1 and C2 with working voltages of 5 volts and 10 volts respectively have a total working voltage of 15V. However, the total capacitance is less than the value of the smallest capacitor.
Do all capacitors'see' the same voltage?
Every capacitor will 'see' the same voltage. They all must be rated for at least the voltage of your power supply. Conversely, you must not apply more voltage than the lowest voltage rating among the parallel capacitors. Capacitors connected in series will have a lower total capacitance than any single one in the circuit.
How a capacitor is used in a voltage multiplier circuit?
Capacitors are connected along with diodes to form the voltage multiplier circuit. Capacitors can be used in many circuits where the output voltage has to be more than the input voltage.

Can a capacitor be used in a DC Circuit?
I need to use a capacitor in a DC circuit where it would store somewhat higher voltage (hundreds of volts). The cheapest way to do that (in my case) is to connect multiple electrolytic capacitors in series, because their maximum voltage is lower than the voltage I want to store. In theory, it should work well with non-polarized capacitors.
What is the effect of connecting capacitors in series?
Connecting capacitors in series increases the total working voltage. For example, two capacitors C1 and C2 with working voltages 5 volts and 10 volts have a total working voltage of Vt = 5V + 10V = 15V. The total capacitance, however, decreases.

Increase Amperage With Capacitors without any change in voltage
A capacitor cannot make a 12V DC 1A power supply into a 12V DC 2A power supply. Amperage in the most basic sense, is what controls the amount of work that can be done from a constant voltage. The circuit that would need to be added to the capacitor would be a resistor with ohm value of 2000 connected to a Darlington pair of transistors.

why do rectified voltage boosts after adding a capacitor?
The rectified AC waveform catches the peaks. The input 9VAC is RMS (Root-Mean-Square average) equivalent -- the actual amplitude of the sinewave is about 40% higher than the RMS average (square root of 2 is 1.414).So on your picture the 9V equivalent is about 70% of the way between 0V and the peaks.

Connect capacitors in *Series* to increase the voltage, but decrease the capacitance. The total capacitance is: 1/Ct = 1/c1 + 1/c2 + 1/c3. If you have 2 equal capacitors, the formula can be simplified so the total capacitance = 1/2 of a single capacitor. The voltage rating for equal sized capacitors can be simply added together.
power supply
When speaking of AC voltage, we normally refer to the RMS value - a "sort of" average. The peak AC voltage will be about 1.4 times the RMS value. When you rectify an AC voltage you will get successive half-waves of the sine wave - this should (I think) give an apparent DC voltage about equal to the RMS value of the AC.
