Hi folks, non-electrician here. Please forgive any inaccuracies in the following. Hopefully my basic point will come across. I am interested in extremely low amp A/C currents, ones that cause no harm to human tissue but are (some claim) useful against microbes, tumors etc. I want to know how best to apply such currents to various areas of the body. E.g. Let's say I have liver cancer and want to flood that organ with high frequency, low amp electricity. Where should I position the anode and cathode? Will the electricity tend to follow veins and arteries, taking the path of least resistance, or will the flesh between the electrodes be (after some time) more or less uniformly imbued with electrical current? If this remains a disputed question among electrical engineers themselves, can someone suggest some basic introductory readings or videos that I might consult? Thanks in advance.
