Answer 1

What is an Electrode?

An electrode is a solid electric conductor that carries electric current into non-metallic solids, or liquids, or gases, or plasmas, or vacuums. Electrodes are typically good electric conductors, but they need not be metals.

Cathode and Anode

In an electrochemical cell, reduction and oxidation reactions take place at the electrodes. The electrode at which reduction takes places is called the cathode. Oxidation takes place at the anode.

Whether an electrode operates as a cathode or anode depends on the direction the cell is operating in.

If a cell is switched from operating galvanically (i.e. outputting energy like a battery) to electrolysis (energy is input to the cell) then its cathode will become its anode and vice versa.

Define Electrode.

$\huge\mathcal\color{navy}{AnsWer}$

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber, and hodos, a way.
