The theory of electronic conduction in solids, which satisfactorily explains the properties of conductors, insulators and semi-conductor,is?
string theory
particle theory
group theory
band theory
Explanation
Band Theory: This theory describes the energy levels of electrons in solids as bands. It explains how the bands (valence and conduction bands) determine the electrical properties of materials.
