Transcription: In this lesson we will discuss semiconductor principles. Resistances, inductances and capacitance are termed passive components. Devices which react to applied signals and produce changes in circuit conditions are known as active components and are called semiconductors or solid state devices. Semiconductor devices can be divided into three broad classes, diodes, transistors and integrated circuits or ICs. Integrated circuits can in turn be classified as linear or digital. Most materials can be considered to be either conductors or insulators. A conductor allows the electrical current to pass ...
