A capacitor can charge to its' maximum OR the voltage applied to it, whichever is LESS.
Yes, voltage matters when charging a capacitor. Capacitor charge rate is proportional to current and inversely proportional to capacitance. dv/dt = i/c So, voltage matters in terms of charge rate, if you are simply using a resistor to limit the current flow, because a larger voltage will attempt to charge faster, and sometimes there is a limit on the current through a capacitor. There is also a limit on voltage across a capacitor, so a larger voltage could potentially damage the capacitor.
basically a capacitor will charge to the input DC level however it will mathematically never happen since capacitors charge at a certain rate the voltage drop across a capacitor will follow the R C time constant or 63% of the applied voltage for a unit time.AnswerIn the case of an a.c. supply, yes, there will be a voltage drop across a capacitor. In the case of an 'ideal' capacitor, this will be the product of the load current and the capacitive reactance of the capacitor.
The capacitor is used to store the charge applied to it.This stored charge can be used to absorb voltage spikes and voltage drops.AnswerIt's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.

(a) what is the total capacitance of this arrangement (B) the charge stored on each capacitor (C) the voltage across the 50 micro farad capacitor and the energy stored in it. 20v and 20+30+50 micro farad
You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.
In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.

A: from a voltage source a capacitor will charge to 63 % of the voltage in one time constant which is define the voltage source Resistance from the source time capacitor in farads. it will continue to charge at this rate indefinitely however for practical usage 5 time constant is assume to be fully charged

A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.

An ideal capacitor is characterized by a single constant value for its capacitance.
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.

Eventually, the capacitor will charge to approximately the source voltage level. As this occurs, the current in the circuit will drop to near zero.
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
