Electrical Conductivity of Metals - ThoughtCo

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. It is these "free electrons" that allow metals to conduct an electric current.

What Causes Electrical Resistance in Metals?

Electrical resistance in metals is caused by the temperature of the metal or impurities in the metal. Both increases in temperature and higher levels of impurities impede the flow of electricity through the metal material. The shape and size of the particular metal also influences its level of resistance to electrical flow.

The "temperature coefficient of resistance" - α - of a material is the increase in the resistance of a 1 Ω resistor of that material when the temperature is increased 1 o C. Example - Resistance of a Copper Wire in Hot Weather. A copper wire with resistance 0.5 kΩ at normal operating temperature 20 o C is in hot sunny weather heated to 80 o C.

Electrical resistivity and conductivity - Wikipedia

Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().. Electrical conductivity or specific conductance is the reciprocal of ...
