Which material is good conductor of heat and electricity? Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. The majority of elements in the periodic table are metals.
Which is good conductor of heat and electricity? Silver is the best conductor because its electrons are freer to move than those of the other elements, thereby making it more suitable for the conduction of electricity and heat than any other element.
What materials are good conductors of heat? Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.
What kind of materials are good at conducting heat and electricity? Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

How is electric charge measured?
The unit for measuring electric charge is the coulomb (C), named after Charles-Augustin Coulomb, an 18th-century French physicist. Coulomb developed the law that says “like charges repel; unlike charges attract.” A coulomb is defined as the amount of charge transported by a current of one ampere for one second.
