2nd Year Physics Chapter 18 Electronics MCQs with Answers

Here you will find 2nd Year Physics Chapter 18 Electronics MCQs with Answers. This is all about Electronics in which we will discuss electrical components like diodes, Biasing and will study different circuits to study the passage of current. Here we will study about P-N Junction that is the boundary between two types of semiconductors. The conversion of AC into DC is known as Rectification. There are some specially designed P-N Junctions like Light-emitting diode, Photo Diode, Photovoltaic Cell. Transistors are studied with their working and types. We will also study Transistor as an Amplifier and as a Switch. The Operational Amplifiers can perform amplification electronically. They can be used as Inverting Amplifier, as Non-Inverting Amplifiers, as Comparator, and as a Night Switch. The last and important term is Logic Gate. There are several Logic Gates we will study in this chapter with some new gates i.e. Exclusive NOR Gate and Exclusive OR Gate. So, this is the brief intro about 2nd Year Physics Chapter 18 Electronics.
