I have a problem. Where do I post this. In the radio section where people who know a bit about electronics are and could understand the humor. In the radio section where people are going to be studying this subject in courses soon? I thought it had better go in the jokes area.

Have a look at this http://img.funenclave.com/f/capacitor-b ... 7hb7zm.jpg

Note: if you need to answer this in a test at some stage in the future, forget this image

Well the theory looks good on paper. It would act a bit different if it was 1.21 jiggawatts.

And I always thought that it was coz the capacitor was "current-ist" (that's like sexist, racist, etc but discriminates on the type of current that approaches it :P )
