Anode is the negative terminal of a battery. It is made of Tungsten which is the same metal used in the filaments of bulbs.
the two types of anode is stationary anode and rotating anode
Holes and electrons
Anode(:
The cathode must be made more positive with respect to the anode.
it is an anode
Water heaters can operate without an anode rod. If tank is not made of steel, then no anode rod is present. If tank is made from steel or glass-lined steel, then anode rod is necessary for long life of tank. Without anode rod, water will rust tank causing leaks and possible failure where tank bursts open and floods house until water is turned off. Anode rods are made of lower noble metals than steel water heater tank. When the two metals are connected together, water reacts with lower noble metal first, so the water dissolves anode rod instead of rusting tank. Anode rods should be checked every two-four years, more frequently when water is softened. Factory-made, gas and electric, steel water heaters come with one or two anode rods installed. Tanks with longer warranties generally have two anode rods. Check manual for specifics. Adding a second anode rod can prolong life of water heater. Ship hulls and propellers, and steel bridges, and other structures that come in contact with water also have anode rods.
The cathode must be made more positive with respect to the anode.
An anode is positive, Cathode is negative. As such, an anode would usually be denoted as + If that is what you meant.
Zinc is the anode.
There is no such thing as anode rays!!
The Cathode is the negative electrode; the anode is the positive electrode
A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
