Question
Figure given below represents a
The correct answer is
unijunction transistor
The question is about identifying an electronic component based on the given diagram. Let's analyze the details:
The figure depicts a device with three terminals: E, B1, and B2. This structure is characteristic of a Unijunction Transistor (UJT).
Reasoning:
- The unijunction transistor has three terminals: an emitter (E), and two bases (B1 and B2).
- In the diagram, the emitter is depicted as a diode symbol pointing towards the body of the device, which is a common representation.
Explanation of Options:
- Zener Diode: This has two terminals and a Zener breakdown characteristic, not matching this diagram.
- Unijunction Transistor: Matches the depicted symbol and terminal configuration in the diagram.
- Diac Trigger: Generally has a different structure with two terminals forming a diode but in bilateral form.
- None of these: Is not applicable as the diagram matches a Unijunction Transistor.
Therefore, based on the diagram and the options provided, the correct answer is a unijunction transistor.
