What is anode and cathode? Elaborate terms related to it.
An anode is an electrode through which the conventional current enters into a polarized electrical device.
This contrasts with a cathode, an electrode through which conventional current leaves an electrical device. A cathode is an electrode from which a conventional current leaves a polarized electrical device.
This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes the direction in which positive charges move.
