I have a question regarding capacitors in general.
Theoretically a capacitor consists of two metal plates in parallell. In the ideal case where there is vaccum between the plates there should be infinite resistance between the two plate.
I am trying to make a capacitor with two aluminium foil and a plastic foil between them. While checking for a possible short circuit I discovered that there is about 20MOHM or more between the plates.
Is this a short circuit or is the resistance of the plastic foil?
any idea about a better insulator? What is the resistivity of kitchen plastic foil?
Thanks
Tom
