What is difference between electrolytic capacitor and electrostatic capacitor?
Electrolytic capacitors use an electrolyte to create a conductive path, allowing for higher capacitance values and lower cost compared to electrostatic capacitors. Electrostatic capacitors store energy in an electric field between two conductive plates without the need for an electrolyte, leading to lower leakage current and higher stability over time.
What two facctors determine the capacitive reactance of a capacitor?
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
Is the electric field in a capacitor constant?
In an ideal capacitor, the electric field is constant between the plates. This means that the electric field is uniform and uniform inside the capacitor.
What is formula for maximum energy stored in capacitor?
The formula for maximum energy stored in a capacitor is given by ( E = \frac{1}{2}CV^2 ), where ( E ) is the energy stored, ( C ) is the capacitance of the capacitor, and ( V ) is the voltage across the capacitor.
How does current flow in a capacitor?
Current does not flow through a capacitor in the same way as through a resistor. Instead, when a voltage is applied to a capacitor, it charges up by storing energy in an electric field between its plates. This stored energy can then be released when the capacitor discharges.

What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
Is leakage through a capacitor undesirable?
yes
Will a capacitor discharge in a open switch?
if the source is switched off there will be leakage slowly discharging the capacitor
How capacitor works practically?
infact what happens in practical capacitor action that air in between parallel plates of that capacitor it acts as a dielectric medium and leakage current starts flowing, that leakage curent is then being bypassed through a conductance in parallel with the capacitor.But in the ideal case that leakage current can't flow due to infinite resistance which can not be provided practically.
Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
Can a capacitor store power continuously?
Yes, but not for ever. A capacitor can never be perfectly insulated and it has a small leakage current, that causes it to discharge eventually.
