How are the capacitances of three parallel plate capacitors related to each other?
The capacitances of three parallel plate capacitors are directly proportional to the area of the plates and inversely proportional to the distance between the plates. This means that if the area of the plates increases, the capacitance also increases, and if the distance between the plates decreases, the capacitance increases.

How does the capacitance of parallel plate capacitors with different surface areas compare to each other?
The capacitance of parallel plate capacitors is directly proportional to the surface area of the plates. This means that capacitors with larger surface areas will have higher capacitance compared to capacitors with smaller surface areas.
How does charge sharing occur between two capacitors connected in a circuit?
Charge sharing between two capacitors connected in a circuit happens when one capacitor releases some of its stored charge to the other capacitor, equalizing their voltages. This occurs until both capacitors have the same voltage across them.
What will happen if you change polarity in parallel circuit?
If you reverse the polarity in a parallel circuit, the components will still function but the direction of current flow through each component will be reversed. This could lead to a change in the behavior of any polarized components in the circuit, such as diodes or electrolytic capacitors. It is important to ensure that the components can handle the reversed polarity to prevent damage.
What is the Difference between like and unlike parallel forces?
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
Is crest related to longitudianl or rarefraction?
The crest of a wave is related to the concept of longitudinal waves. In longitudinal waves, particles of the medium vibrate parallel to the direction of wave propagation. Rarefaction, on the other hand, refers to the region of a longitudinal wave where the particles are spread out.
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 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.
Why are capacitors parallel?
Capacitors are said to be connected together "in parallel" when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors. The voltage (Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then,Capacitors in Parallel have a "common voltage" supply across them giving: VC1 = VC2 = VC3 = VAB = 12V
How does the capacitance of parallel plate capacitors with different surface areas compare to each other?
The capacitance of parallel plate capacitors is directly proportional to the surface area of the plates. This means that capacitors with larger surface areas will have higher capacitance compared to capacitors with smaller surface areas.
What is the advantage of using 2 or more capacitors in parallel in circuits instead of one larger capacitor?
When capacitors are connected in parallel, you add up their capacitances to obtain the overall capacitance of that 'bank'. The main reason for using two capacitors in parallel when decoupling, is that they have a lower overall inductance (electrical resistance in essence) to one large capacitor, which improves the decoupling effect. Using two capacitors also provides better high-frequency filtering for the power bus. One minor advantage of this, is that, you can obtain a certain redundancy when using two smaller capacitors in parallel, instead of only one, as if one capacitor fails, the other still acts to decouple the circuit, to a certain extent.

What is schematic symbol of the paper capacitor?
paper capacitors are non polar, so they have the same symbol as any other non polar capacitors like ceramic disc, two parallel lines.
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
How does a Colpitts oscillator work?
A Colpitts oscillator is the electrical dual of a Hartley oscillator. In the Colpitts circuit, two capacitors and one inductor determine the frequency of oscillation. The feedback needed for oscillation is taken from a voltage divider made by the two capacitors, where in the Hartley circuit the feedback is taken from a voltage divider made by two inductors (or a tapped single inductor). (Note: the capacitor can be a variable device by using a varactor). Oscillation frequency The ideal frequency of oscillation for the circuit is given by the equation: where the series combination of C1 and C2 creates the effective capacitance of the LC tank. Real circuits will oscillate at a slightly lower frequency due to junction capacitances of the transistor and possibly other stray capacitances
Define parallel and explain how the slope of 2 parallel lines would be related?
I always remembered parallel line because of the 2 "L's" in parallel. They are perfectly parallel to each other and will never intersect. The slope of a line is the rise over run, or rise/run. Therefore if both lines are parallel, the slopes of the lines are the same.
How are motor start capacitors rated?
Motor start capacitors are rated with two main values. One is capacitance in micro farads and the other is in voltage.
Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.
Are the lines of latitude of parallel or perpendicular to each other?
They are parallel to each other.
