NCERT Solutions for Class 12 Physics Chapter 14 Semiconductor Electronics: Materials, Devices and Simple Circuits


A material that is neither an insulator nor a full conductor that has an intermediate level of electrical conductivity and in which conduction takes place utilizing holes and electrons. Most of the questions will consist of an n-type semiconductor device and the majority of careers and dopants. We will be seeing what will happen when a p-n junction is forward biased and reverse biased. Students will be seeing questions based on calculating the output frequency of a half-wave and full-wave rectifier and even have questions on finding the input signal and base current of a CE-Transistor amplifier. We will even help you find out the output AC signal if two amplifiers are connected in series. If a p-n photodiode is fabricated, will it detect wavelengths? Students even have questions on OR and AND gates where you will be figuring out which of the given circuits comes under these two categories. The chapter has additional exercises containing questions based on finding several holes and electrons in atoms of silicon, Indium, and arsenic. We have questions about calculating the ratio between conductivity at two different temperatures.
