A capacitor with low leakage typically refers to a ceramic capacitor, specifically those with C0G or NPO dielectric material. These types of capacitors have very low leakage currents due to their stable and non-polarized characteristics.
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.
