There is such an issue in dielectric capacitors as dielectric absorption.Usually it is regarded as drawback.I have some questions on it: 1)Does dielectric absorption allow you to store more charge at the same voltage?And therefore materials with the same dielectric constant and dielectric strength but higher dielectric absorption have larger energy density?If yes what is mechanism of it?Or higher dielectric absorption means higher voltage?
2)What is relation between dielectric absorption in dielectrics and space-charge polarisation?Is it allways the same thing?
