Explain the following difference that exists among the materials used below terms as used in analogue electronics, conductor, semiconductor, insulator ?

Answer the questions

In analogue electronics, there are significant differences among the materials used, namely conductors, semiconductors, and insulators. These differences primarily depend on the ability of a material to conduct electric current. 1. Conductor: A conductor is a material that allows the free flow of electric charge. It has a high density of free electrons that are easily movable within the material. Some common examples of conductors include metals like copper, silver, and aluminum. The presence of delocalized electrons in the outer energy levels of their atoms enables efficient conduction of current. Conductors are used in analogue electronics for various purposes like wiring, circuit connections, and power transmission due to their excellent conductivity. 2. Semiconductor: Unlike conductors, semiconductors have an intermediate conductivity. They possess lower densities of charge carriers (electrons or holes) compared to conductors. Pure semiconductors, such as silicon (Si) and germanium (Ge), exhibit poor conductivity at room temperature. However, their conductivity significantly improves when certain impurities, known as dopants, are added through a process called doping. The electrical properties of semiconductors can be easily manipulated, making them vital for the creation of electronic devices like transistors, diodes, and integrated circuits
