An ideal capacitor integrates the voltage across it. If you look at its frequency response you'd see that it's like a delta function at 0Hz, which represents a time domain integration.

When capacitors ate connected in series the capacitance increase or decrease?
Capacitors in connected in series result in a higher voltage rating, but lower capacitance. Two 470uF 50V capacitors connected in series will give you a total of 235uF, but you can put up to 100V across the series combination. Two 470uF 50V capacitors connected in parallel will give you a total of 940uF, across which you can put 50V (the voltage rating does not change for capacitors in parallel).
What are the possible remedies against corona because of extra high voltage?
increase the size of conductor ,provide the hallow conductor,increase the critical disruptive voltage bv providing shunt capacitors. these capacitors increases the power capacity of the line.
What is the principle of operation of a ballast?
Older ballasts with an iron core are basically an autotransformer. They transform voltage to a higher voltage with a single winding. Electronic transformers increase voltage with capacitors and diodes.
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.
What is definition of residual voltage?
Net voltage in the Neutral of a three phase electrical system is called residual voltage.
How voltage doubler works?
The voltage doubler works by charging alternate capacitors on alternate half-cycles. Since the capacitors are in series, the voltage doubles.
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).
Do magnets affect capacitors?
Yes, they do, but their affect is minimal. Magnets with their magnet fields affect inductors profoundly, but don't do to much to capacitors.
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 is psychology related to capacitors?
Psychology and capacitors are not directly related. Psychology is the study of the mind and behavior, while capacitors are electronic components that store electrical energy. However, both fields involve the understanding of systems and processes, albeit in very different contexts.
4 capacitors 2.2uF 3.3uF 4.7uF and 5.6uF are connected in series with a power supply of 200 volts dc what is the voltage across each capacitor what is the formula?
Putting capacitors in series and then applying a DC voltage to them is not entirely useful. The voltage will cause a small current to flow into the capacitors, charging them to a total cumulative voltage of 200V. No further current will flow. If a meter is applied to one of the capacitors it's charge will cause a voltage measurement but it will quickly drop as the current flowing into the meter discharges the capacitor.
Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
An electrical tool that increases or decreases the voltage in an electrical current is?
capacitors
How only capacitors can give smooth ac voltage waveform when used in ac circuits?
Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out.
Is there a negative and positive polarities on capacitors?
Electrolytic and tantalum capacitors both have polarity.
Why is it important for all capacitors to display on their cases the maximum working voltage?
If the applied voltage exceeds they Max working voltage than capacitor can blow.
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.
