Biasing a BJT means establishing the desired values of VCE and IC so that the amplifier will have the proper gain, input impedance, undistorted output voltage swing, etc. These values of VCE and IC are known as the quiescent operating point or Q- point.The methodology is based on fundamental laws governing linear circuits and methods of their analysis. The method involves creating models of the faulty elements ...Electronic Devices and Circuit Theory. Boylestad. BJT AC Analysis. Chapter 5. Ch.5 Summary. BJT Transistor Modeling.

The schematic you show here is from LTspice, I believe. It's default NPN BJT has β = 100 β = 100 and ISAT = 100aA I SAT = 100 aA. Your "EveryCircuit" link is very unlikely to use the same default model. So LTspice probably will simulate different values. Just FYI.To convert a BJT into a short circuit we know that all DC voltage sources are short circuited. This statement doesn't make sense. The BJT is not being converted into a short circuit. Your professor is performing a standard ac analysis at the dc operating point of the emitter follower.electronic circuit with one terminal being common to both the input and output. Each method of connection responding differently to its input signal within a circuit as the static characteristics of the transistor vary with each circuit arrangement. • 1. Common Base Configuration - has Voltage Gain but no Current Gain. • • 2. ….
