Khadija Brohi answered . Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. Iron, being a metal, also has free electrons in its valence shell that, with some force from the attached battery, start flowing through it. We all know, that the smallest unit of all elements is an atom. Iron; Iron is a good conductor of electricity, but not as good as silver. Properties of Metals.

Iron is not as good a conductor, but if we talk about iron conductivity in general, it can be considered a fairly good conductor of electricity with it being 17% conductive. I also used one of the bars of galvanized steel that are about 4 feet tall and 1/2 a inch wide and 1/8 an inch thick that is used to tighten the fencing. The two most commonly used structural metals are iron and aluminium. I used the wire that is used to build a metal fence. The importance of good and bad conductors of heat. On the other hand, a bad conductor of electricity is one that prevent free flow of electric current through it. Physics. Gases are not good conductors of electricity because the … Dynamic electricity, or electric current, is the uniform motion of electrons through a conductor. Mercury is an excellent liquid conductor. In other words, a good conductor has high conductance and low resistance, whereas a bad conductor has low conductance and high resistance. Static electricity is unmoving (if on an insulator), accumulated charge formed by either an excess or deficiency of electrons in an object. I am trying to make a electric fence from scrap so my dogs will stop getting out.

Metals are good conductors, making them important in electrical appliances and for transmitting an electric current over a distance with little lost of energy. Mercury is a better conductor than iron as it has lower resistivity comparing to iron. Explain in terms of metallic bonding, why iron is a good electrical conductor? That is why the parts of electrical objects that need to let electricity pass through are always made of metal. Rust is a mixture of iron oxides, including Fe2O3, FeO(OH) and FeO. Thus, this material finds use in many instruments. They are also the richest metals in the world.

... Leaving the spaces between the railway bars which are made of iron to avoid the train accidents where iron is a good conductor of heat, So, it expands and twists by the heat.

In its pure state it will not conduct electricity, but if impure and if it has some free iron still in its matrix it may conduct electricity, depending on how much free iron is present. I used the galvanized steel about 30 feet of it. ... Usages of good and bad conductors of heat.
