In semiconductors, conductance is lower compared to conductors due to the presence of energy band gaps that restrict the movement of charge carriers. Conductors have high conductance because they have a high density of free electrons that can move easily and carry electric current.
* Any element where the valence band of electrons overlap the conductance band is called conductors * The band gap between the Valance bond and conductance band is very low * Electrons are more in Conductance band
No, not all metals are good conductors. Some metals, such as copper and aluminum, are excellent conductors of electricity and heat due to their large numbers of free electrons. Other metals, like lead and stainless steel, are poor conductors because their electrons are not as free to move.
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
Corrected conductance is calculated to account for the impact of temperature on the conductance of a substance. Conductance is temperature-dependent, so correcting for this allows for a more accurate comparison of values across different temperatures. It helps to standardize conductance measurements and make them more reliable for analysis.
The conductance of a wire is the reciprocal of its resistance. Therefore, for a wire with a resistance of 400 ohms, the conductance would be 1/400 siemens, or 0.0025 siemens.

Group 14 elements such as silicon or germanium generally act as semi-conductors. Boron, a group 13 element, normally acts as a dopant in semiconductors.
Most metalloids are semi-conductors.
