This book provides the reader with a wide range of information in the interdisciplinary subject area of composite materials. The book consists of thirteen chapters. Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators (such as ceramics). Whereas semiconductors allow a moderate flow and insulators exhibit low conductivity. A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable.

The topic covered is "circuits and conductors". Electric charge exists on the surface of conductors: Electric charges are absent in insulator. In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. Introduces insulators and conductors, discussing what they are and how they work. These QSH states can “hybridize” and open up a band gap, transforming the initially insulating materials into electrical conductors. Electrons in an atom can have only certain well-defined energies, and, depending on their energies, the electrons are said to occupy particular energy levels.
