How charging and discharging of capacitors happened?
in the capacitor they have constant voltage wen supply is given the capacitor get charged(high voltage)and discharge energy wen the voltage is low below the applied voltag.
Which is most dangerous between high capacitance and high voltage regarding capacitors?
As from a human contact perspective: High voltage alone poses not much of a danger if the current is very low. It may be rather uncomfortable but a normal healthy person with no heart disorder should not be endangered with high voltage and very low current. Low voltage capable of high current poses not much of a threat to humans either as long as our skin is dry. The combination of High voltage capable of high current is deadly to most humans. A capacitor of high capacitance is normally a low voltage one. High voltage is normally found only in very low capacitances. Which of them that are most dangerous is a bit difficult to answer without more information. A high capacitance capacitor with low voltage may explode violently when connected to high voltage source capable of high current. This is very dangerous. Although not killingly dangerous, you can easily loose an eye or two. A high voltage capacitor is not likely to explode due to high voltage. The current it carries when charged can be rather uncomfortable but not likely dangerous as in life threatning. This because the leads are so close together (current would need to go across heart in order to cause lethal problems in normal healthy people) so unless you force yourself to hold one lead with one hand and then touches the other lead, then it poses as no particular threat. Even if doing that, the current carried by the capacitor is not likely to be able to cause heart to stop. It might make a jump though. I would place my bet on High Capacitance due to the danger of explosion. Be sensible when experimenting with electronics, and you should not need to think about this :-)
What is the difference between an inductive low pass filter and a capacitive low pass filter?
Where you are measuring. A simple filter will be two elements - a capacitor or inductor and a resistor. A capacitor will tend to "trap" low frequencies. In the case of a lowpass filter made of a capacitor and resistor, the output voltage will be measured across the capacitor. Inductors are the opposite, so the output would be across the resistor.
What electronic device can hold an electrical charge for a period of time and can smooth the uneven flow of electricity through a circut?
That would be a capacitor, which stores charge on it's plates when exposed to a voltage and discharges it when exposed to an input resistance. It can smooth ripples in current by it's tendancy to maintain voltage, so it can simulate the average violtage over time by discharging when the circuit voltage is low.
What is the function of the resistor into capacitor?
A RC circuit is a simple filtering circuit. The impedance of R will stay the same across the frequency band. The impedance of C will vary according to 1/jwC (j = i = imaginary number, w = omega/frequency in radians, C = capacitance in Farads). As frequency varies from low frequency to high frequency, an increasingly smaller amount of the signal voltage will "drop" across the capacitor. This is known as a first order (one reactive element, the capacitor) low pass filter if the desired signal is measured across the capacitor. If measured across the resistor, this would be a first order high pass filter. Edit: if you are talking about ESR (equivalent serires resistance), it is a parasitic component inside a capacitor. Theoretically, you don't want it but it's there.
Can you use a high voltage capacitor on a low voltage battery?
Yes. You just don't want to exceed the voltage rating of the capacitor.

Why does the ratio of the voltage to current in capacitor and inductor depend on frequence?
The ratio of voltage to current, or the impedance, of reactive elements such as capacitors and inductors depends on the frequency of the applied wave because they store energy, and the amount of energy they store is directly related to the frequency of the applied waveform. When a DC voltage is applied to a capacitor, the current through the capacitor initially will be large, and will decay down to zero as the capacitor charges. Also, the voltage across the capacitor will be small initially and will increase over time to be equal to the applied voltage. This behavior results in a varying impedance when an AC waveform is applied. At a very low frequency, the capacitor will charge up and discharge similarly to if a DC source was switched into the capacitor for a long period of time there would be a large voltage drop, and small current = high impedance). As the frequency increases, the capacitor will appear more like a DC source was initially switched into the capacitor (low voltage drop and high current = low impedance).

Do capacitors increase voltage?
Capacitors store charge. The formula is Q=CV. They do not by themselves increase voltage or current. If a capacitor is connected to a load, it can provide a large transient current in respond to sudden demand. It can only average out demand spikes, it cannot provide more current on average than is available from the supply. In a circuit such as a power supply, a capacitor can store charge, and hence preserve an output voltage, during periods when the input voltage falls e.g. at zero-crossing of an AC supply. It can also be used in a voltage-doubler or inverter circuit, possibly together with an inductor, to generate a high voltage from a low one. But it, by itself, does not increase voltage, it merely collects charge like a funnel collecting raindrops to provide a steady stream of water. Electrikals...

What causes high and low currents?
In electricity? High voltage ,high currents. Low voltage, low currents.
Why capacitor behave as open circuit against alternating current?
Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit. Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.
