• 4. How can you distinguish between an NPN and a PNP bipolar junction transistor (BJT) using a multimeter?
  In diode mode, an NPN transistor will show a forward voltage drop from base to emitter and base to collector, while a PNP will show a forward drop from emitter to base and collector to base. The arrow in the schematic symbol points outward for NPN and inward for PNP.
• 5. What is the primary function of a resistor in an electronic circuit?
  A resistor limits or regulates the flow of electric current, helping to control voltage levels and protect other components.
