Electrical conductivity is the measured amount of current generation created on a metal target’s surface. More simply, it is how easily an electrical current can flow through a metal. Which Metals Conduct Electricity? While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive.
Which Would Be the Best Insulator: Diamond, Gold, Lead or Concrete? By John Papiewski; Updated April 25, 2017 . ... the conductor carries electric current where it needs to go, and the insulator safely prevents electricity from wandering to other wires or conductive materials. Conductors carry electrical current with very low resistance.
Lead is 12th on the list of conductive metals, with Silver, Copper and Gold being the best conductors. The better conductors have to do with available electrons in the conduction band of the metal.
Best Answer: Rather than copy and pasting from wikipedia Ill give you a real answer! Yes lead is conductive, but not very good one. It has a higher resistivity than copper or aluminium. Circuitboards etc are usually soldered with an alloy of lead and tin. Europe has now banned lead solder though, so other ...
The differences in electrical conductivity of various materials used in marine electrical products are often not well understood. Making assumptions about the electrical conductivity of a material because it looks similar to another conductive material of known ampacity can lead to disastrous results.
Lead (/ ˈ l ɛ d /) is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed ...

Pencil lead, contrary to its name, contains no lead, but graphite and clay, the relative amounts defining the hardness (more graphite equals softer leads). Graphite is also a conductor, and thus pencil leads are conductors.
Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about.
Their calculation for freon filled polyurethane of density 1.99 lb/ft 3 at 20°C gives a thermal conductivity of 0.022 W/mK. The calculation for CO 2 filled polyurethane of density 2.00 lb/ft 3 gives 0.035 W/mK .
