BJT stands for **Bipolar Junction Transistor**. It is called **bipolar** because it uses both electrons and holes as charge carriers in its operation. The term **junction** comes from the two PN junctions inside the transistor. And **transistor** means it can amplify or switch electrical signals.
So, the name **BJT** highlights its key features:
- **Bipolar** → Uses both types of charge carriers (electrons and holes).
- **Junction** → Has two PN junctions.
- **Transistor** → Works as an amplifier or switch.
