Match the following conductivity range in Ω−1m−1 of materials
Open in App
Solution
The solids with conductivities ranging between
104 −107Ω–1m–1 are called conductors.
If the conductivity of metal is
107 Ω−1m−1they are good conductors.
Insulators have very low conductivity range of 10−20 −10−10Ω−1m−1
Semi conductors have moderate conductivity range of10−6−104Ω−1m−1
