A transistor has ___________

Solution (By Examveda Team)

A transistor has two pn junctions.

In a bipolar junction transistor (BJT), which is the most common type, there are two pn junctions: one between the emitter and the base, and another between the base and the collector.

These two junctions are crucial for the transistor's operation, allowing it to amplify or switch electronic signals.

Transistors do not have one, three, or four pn junctions; the correct number is two.
