As an example, copper is a good conductor as it provides a low level of resistivity, its cost is not too high, and it also provides other physical characteristics that are useful in many electrical and electronic applications. The resistivity of copper is around 1.7 x 10-8ohm metre (or 17...
At 200C the resistivity value for silver is 1.59×10-8, for copper 1.68×10-8. All the resistivity values for various materials can be found in atable. Wood is considered as a high-insulator but this varies depending upon the amount of moisture present in it. In many cases, it is dif...
