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.

∙ 12y agoWhen you connect two capacitors, or any other component for that matter, in parallel, they will have equal voltage. Voltage is similar to pressure, so imagine you have two air containers with different sizes and with one input tied together. If you provide an air pressure, the same pressusre fills both containers and they end up reaching equilibrium at the same pressure for all. The pressure is the same for all, but the amount of air is different between the two.
Similarly, two different size capacitors can hold different amount of charge under the same voltage. If the capacitors are equal, then the charge is equal for parallel capacitors too.

How do you find voltage across capacitors in a serial parallel circuit?
Voltage across all parallel capacitor's is same i.e. it is equal to supply voltage, it can be measured using digital volt meter (any high input impedance volt meter). When capacitors are in series; voltage drop depends on charge stored in the capacitor. it can be given by the formula V x V = 2 / (joules x capacitance). This voltage can also be measured using digital volt meter.
What if four capacitors of equal value are in series?
The total capacitance is one fourth of the capacitance of the individual capacitors. The voltage rating is four times the voltage rating of the individual capacitors (however to prevent uneven charging of the four capacitors and failure of one or more they must be paralleled with a voltage divider composed of four equal value resistors).
What are uses of series and parallel capacitor combination?
Capacitors may be connected in series to provide a capacitance with an effective working voltage higher than that of any of the individual units, (but the effective capacitance is less than that of any individual.) Capacitors may be connected in parallel to provide an effective capacitance value greater than that of any of the individual units, (but working voltage is equal to the lowest among the individuals).
How do you calculate the value of two capacitors conected together?
If the internal capacitors are separate, I mean that there are 4 terminals, a separate positive and negative for each internal cap then you can connect them in two ways. If you connect them in parallel (positive to positive and negative to negative) you just add the values together, so if each is 100UF they total 200Uf and the voltage you can apply is whatever is rated on the body. If you want to increase the voltage so you can apply higher voltage you connect them in series, one of the negatives connects to the others positive and the remaining inputs are connected to the circuit (and if each is equal in value) you divide by two so they would only be 50UF in capacitance but the total voltage you can apply is double the rated level on the body. If the caps are of different values it gets more complicated, you have to calculate the C total buy using the following formula: 1/C total = 1/C1 + 1/C2. Then the voltage dropped across each cap is proportional to the values you calculated above. Remember, the total voltage will be dropped across the caps proportionally so if the caps are rated at 50V for example and they are not equal values, you can't connect them up to 100V because the larger of the caps will have more than 50V across it because of the mis-matched value of each.
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
Physics numerical four capacitors each of 2micro farad are connected in such a way that the total capacitance is also 2 micro farad show what combination gives this value?
In order to connect four 2 microfarad capacitors such that the total capacitance is still 2 microfarads, connect two pairs of capacitors in series, and then connect the pairs in parallel. It does not matter, since all four capacitors are equal in value, if the center point is connected together or not.
What is formula for connecting 2 capacitors in parallel?
The result of connecting two capacitors in parallel is a new capacitor whose capacitance is the sum of the values of the two you connected up. Note. the safe working voltage is equal to the lower of the two working voltages on the two capacitors.
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.

What is is the geostrophic wind?
Air that is high in the atmosphere which blows parallel to the isobars (lines that connect areas of equal pressure)
Five capacitor replacement rules?
To replace a capacitoræyou must make sure that the replacement capacitors voltageæis equal or greater than the original, the microfarad (or strength rating)æis +/- 10 % of the original runæcapacitor, the microfarad of theæstart capacitor is +/- 20% of the original, for capacitors that are wired in parallell the microfarad must be equal to the sum of the individual capacitors, for capacitors that are wired in series the microfaradæis equal the reciprocal of the sum of the reciprocals of the individual capacitors.
How do you draw a trapezoid?
Draw two parallel lines of unequal length, and connect their end points. If you have a right angle, it is a right trapezoid. If the non-parallel sides are equal in length, it is an isosceles trapezoid.
Why are isotherms generally parallel across the US?
Isotherms connect points of equal temperature on a weather map. The lines of isotherms naturally run parallel to each other. Their spacing indicates temperature variance.
Two voltage sources can be connected in parallel when they are equal in?
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
What electrical component would be measured in farads?
The faraday is the unit used to denote a quantity of electrical charge. It is equal to the charge of one mole of electrons, and is also equal to 96,485.3365 coulombs. It is not to be mistaken with Faraday's constant, a related number denoting electrical charge.
How does a capacitor get charged?
a capacitor is used to store charge for longer period of time.in odder to understand that how a capacitor gets charged consider two parallel metal plates.these plates are neutral having equal amount of positive and negative charges.now connect these plates to the opposite terminals of a battery.the electrons present in the plate connected to the positive terminal of a battery will be attracted by the positive terminal leaving the plate positively charged.now these electrons are pushed by the battery to its negative terminal which repels these electrons to the plate connected to it making it negatively charged. now the battery is disconnected.so in this way the plates of a capacitor gets charged.as these plates have opposite charges stored on them force of attraction exist between them enabling a capacitor to store charge for longer periods of time.
What if four capacitors of equal value are in series?
The total capacitance is one fourth of the capacitance of the individual capacitors. The voltage rating is four times the voltage rating of the individual capacitors (however to prevent uneven charging of the four capacitors and failure of one or more they must be paralleled with a voltage divider composed of four equal value resistors).
