A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
what is flying capacitor
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.

when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
yes
if the source is switched off there will be leakage slowly discharging the capacitor
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.
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.
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.
