DEFINITION OF AN ANODE. âAn ingot of sacrificial metal attached to the underwater hull of a narrowboat or canal boat which corrodes due to electrolysis more readily than the hull and propeller. Magnesium anodes are used for boats in fresh water.Aluminium anodes are used for boats in brackish water.nodes will offer protection based on the Noble Series of metals. The theory is that by attaching a piece of metal to the hull that is more reactive than the hull itself then this piece of metal will corrode first. For our inland waters we use sacrificial magnesium anodes for protection.
Pure water is an insulator, since it doesn't contain any charged particles to act as conductors. However, water is an excellent solvent for charged particles like salts, so it's unheard of to find pure water in nature.
Conductor are materials which electric current can flow freely, and Insulator are materials which electric current cannot flow freely. Metals such as copper typify conductors, â¦ while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material. conductor is that one which allows the flow of electric current through it. An inductor is also a conductor but in the form of a coil used in varying current circuits. An in â¦ ductor's role is not to conduct electricity; it is used in alternating current circuits and control it without much power loss.
