Question

Types of electrode and their application in electrochemistry

Answer 1

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 the Greek words elektron, meaning amber (from which the word electricity is derived), and hodos, a way.[1][2]

The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity
