Question

Are all transistors the same?

Answer 1

1. No, all transistors are not the same.
2. They are broadly divided into $3$ types based on their structures.
3. They are namely: Bipolar Junction Transistors (BJTs), Field Effect Transistors (FETs), and Insulated Gate Bipolar Transistors (IGBTs).
4. The Bipolar Junction Transistors are further classified as PNP and NPN depending on their construction.
