Project 3.1: The Transistor

This is the support page for Project 3.1 from Complete Electronics Self Teaching Guide with Projects. The circuit in this project is used to measure the beta of bipolar transistors.

Parts List

  • One multimeter set to ľA
  • One multimeter set to mA
  • One multimeter set to measure DC voltage
  • Resistors
    • One 10 kΩ resistor
    • One 510 ohm resistor
  • One 2N3904 transistor
  • One 1 MΩ potentiometer (Chose between potentiometers with lugs that you need to solder wires to, or potentiometers with pins that can be inserted directly into the breadboard.)
  • One breadboard
  • One terminal block
  • One battery snap connector
  • One 9 V battery (or a lab power supply)
