Hi guys! Hope all is well. I just started learning about NPN transistors, which i think are pretty cool. Like all newbies, I have a question about them. In the schematic below, why did the designer of the circuit decide on using a 10K resistor for the base current? What is the math behind it?
The transistor is a 2N3904 NPN Bipolar Junction Transistor.
Thank You for your answers.
