What Does ER Stand For?
ER stands for Electrical Resistivity
Electrical Resistivity (ER) is a fundamental property of materials that quantifies their ability to resist the flow of electric current. It is defined as the resistance encountered by a uniform electric field through a material of unit length and unit cross-sectional area. Measured in ohm-meters, resistivity is influenced by factors such as temperature, material composition, and physical structure, making it a critical parameter in applications ranging from electrical engineering to geophysics and materials science. Understanding the resistivity of a material helps in the selection of appropriate materials for electrical applications and in evaluating subsurface conditions in geological studies.
