Q

What is the meaning of the term “alpha” with regard to bipolar transistors? The change of:

🔍 Key Concepts

• Relationship between collector, base, and emitter currents in a bipolar junction transistor (BJT) • Difference between alpha (α) and beta (β) in BJTs • Why the term gate is associated with FETs (field-effect transistors), not BJTs

💭 Think About

• In a BJT, which two terminals are directly related by alpha (α): is it base–collector, base–emitter, or collector–emitter? • Think about beta (β): it’s defined using base current and collector current. If beta uses base current, which different pair of currents would alpha use? • Look at the option that uses a terminal name that does NOT belong to BJTs; can that option be correct for a BJT parameter?

✅ Before You Answer

• Identify which answer choices involve base current and which involve emitter current • Recall: β relates collector current to base current; α relates collector current to a different current • Eliminate any option that mentions gate because BJTs have emitter, base, and collector, not a gate terminal
