Aluminum electrolytic capacitor C when the cathode capacitance C is very large compared with the anode capacitance C. This requirement is given when the cathode capacitance C is approximately 10 times higher than the anode capacitance C. This can be easily achieved because the natural oxide layer on a cathode surface has a voltage proof of approximately 1.5 V and is therefore very thin. Although the present article only refers in essence to aluminum electrolytic capacitors with non-solid electrolyte, an overview of the different types of aluminum electrolytic capacitors is given here in order to highlight the differences. Aluminum electrolytic capacitors are divided
Electrode for advanced purposes in research and investigation. Electrode An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: "elektron", meaning amber (from which the word electricity is derived), and "hodos", a way. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. An electrode in an electrochemical cell is referred to as either an "anode" or a
