I want to know the answer to the following question:
What sort of components can be added to the equivalent circuit of a capacitor in order to deal with leakage current and parasitic effects?
All the background I'm provided with is that "Some of these, such as leakage current and parasitic effects are linear, or can be assumed to be linear, and can be dealt with by adding virtual components to the equivalent circuit of the capacitor.". Is that enough to answer the question?
Answer: yes
