Electrical Resistivity of Common Dielectric Materials
Dielectric materials have high electrical resistivity, meaning they offer significant opposition to the flow of electrons. This property is crucial in various applications, such as capacitors and insulators in electronic circuits.
The following table provides a comprehensive list of electrical resistivity values for common dielectric materials at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
