Draw a BJT circuit which acts as a switch? why is Vce(sat)=0.2V? what will happen if resistor is connected in between emitter & ground point & many other related Q?

Question

Accepted Answer

A BJT circuit can act as a switch with Vce(sat)=0.2V. Adding a resistor between emitter and ground affects the switching speed.

BJT circuit can be configured as a switch by connecting the base to a voltage source and the collector to the load.
When the base-emitter junction is forward-biased, the transistor turns on and allows current to flow through the collector-emitter path.
Vce(sat) is the voltage drop across the collector-emitter path when the transistor is fully on. It is typically around 0.2V for a BJT.
Adding a resistor between the emitter and ground can affect the switching speed of the transistor. A smaller resistor will allow the transistor to switch faster.
BJT switches are commonly used in digital circuits and power electronics applications.
