The ideal capacitor has no resistance either in series or in parallel with it. What you are therefore asking about is non-ideal behavior. Truly modeling all the non-ideal characteristics of any real part is impossible. Everything has some series inductance, some series resistance, some leakage resistance, and some parasitic capacitance. Then ...
An LCR meter is a type of electronic instrument or device that measures resistance, inductance, and resistance of a conductor. The use of this device is principally in troubleshooting and maintenance work, such as checking for broken wires and shorts. An LCR meter can determine if a capacitor is defective or not.
An ideal capacitor has no resistance and no inductance, but has a defined and constant value of capacitance. The unit used to represent inductance is henry, named after Joseph Henry, an American scientist who discovered inductance. Parasitic inductance. Parasitic inductance is an unwanted inductance effect that is unavoidably present in all real electronic devices. As …
LCR meters measure inductance (L), capacitance (C), and resistance (R) – hence the name. LCR meters can be powerful tools for supporting the development of electronic circuits. However, to get the best from your meter, you must understand precisely how they work and the benefits they bring to the development process.
The resistance, R, in this expression is a measure of how the kinetic energy of the moving charges, i.e., the current, is converted into thermal energy. This equation is immediately recognizable as relating to a single-degree-of-freedom, damped harmonic oscillator, which is one of the most well-studied problems in engineering and physics.
To measure the capacity and the internal resistance accurate, the measure frequency must be chosen so that the reactance and resistance are approximately the same. The phase difference between the capacitor …

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste.
