Home > Anode

An anode is the positive electrode in an eletrolytic system or circuit. Literally, the path through which the electrons ascend out of an electrolyte solution.

In electrochemistry, the anode is where oxidation occurs and is also the negative discharge plate in an electrochemical cell. In charge mode the flow reverses and this plate becomes the cathode. In electronic circuits such as a cathode ray tube or a diode, the anode is the positive plate.

In solution negatively charged particles - Anions, flow to the anode. In tubes or circuits electrons flow to the anode.

The opposite of an anode is a cathode.

Electrochemistry ElectricityElectricity is a property of certain subatomic particles, such as electrons and protons, that gives rise to attractive and repulsive forces between them. It is one of the four fundamental forces of nature, and is a conserved property of matter that can be
