Web1 dag geleden · If a material can conduct electricity efficiently, the conductivity value is high. Its SI unit is Ohm-1 m-1 and is represented by κ or σ or γ. For lead metal, the conductivity value is 4.55 * 10 6 Ohm-1 m-1 at 20°C. Silver metal has the highest conductivity of 6.3 * 10 7 Ohm-1 m-1 20°C. Question: What is the resistivity of Lead? WebIncreased volume conductivity generally means decreased surface resistance. The graph below illustrates the internal resistance of various substances. To reduce internal resistance of a polymer it is quite common to add a conductive substance such as carbon black. The necessary amount varies depending on the desired end properties of
