What is an anode made from?
Anode is the negative terminal of a battery. It is made of Tungsten which is the same metal used in the filaments of bulbs.
Can the water heater operate without a sacrafical annode?
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.
What does HGE mean when its on the iside of a ring?
H.G.E. stands for hydrostatic gold plating/gold electroplating. A ring that has those letters engraved on the inside isn't made of gold. It's made of some other metal that has been layered over with gold plating. The plating wears away with time. But the thicker the plating, the longer the lifespan. And H.G.E. is the thickest plating around for jewelry.
Anode current in an thyristor is made up of?
Holes and electrons
What is Loony made of?

What is reversed conditioning?
The cathode must be made more positive with respect to the anode.
What is reverse bias condition?
The cathode must be made more positive with respect to the anode.
Do BB's contain lead?
Copperhead BBs are made of steel with copper plating.
Do pennies have copper in them?
yes, they're made of a zinc core with a thin layer of copper plating. The plating only makes up 2.5% of the coin's weight, though.
What a 1943 wheat penny looks like?
It has the exact same design as all other wheat pennies, but it was made out of steel instead of copper. They were coated in zinc when new which made them shiny, but the plating wore off quickly so most steel cents are a dull gray.
Do Copperhead BBS contain lead?
Copperhead BBs are made of steel with copper plating.
What are mouthpieces made of?
They are typically made of brass and finished with a silver plating. Some mouthpieces are gold-plated.
