1. What is Transistor?
A transistor is a semiconductor device used to amplify or switch electronic signals. It has three terminals and is a key component in electronic circuits like amplifiers, switches, and oscillators.
2. What is the full form of BJT?
The full form of BJT is Bipolar Junction Transistor. It is a type of transistor that uses both electron and hole charge carriers for current conduction.
3. What are the types of BJT Transistor?
There are two main types of BJT transistors: NPN and PNP. Both types have three layers and terminals: emitter, base, and collector, but differ in current flow direction.
4. What are the terminals name of BJT Transistor?
The three terminals of a BJT transistor are Emitter, Base, and Collector. Each terminal plays a specific role in the transistor’s operation for amplification or switching.
5. What is Emitter in Transistor?
The emitter is the terminal that supplies charge carriers (electrons or holes) into the base. It is heavily doped to inject a high number of carriers into the transistor.
6. What is Base in Transistor?
The base is the thin, lightly doped central region of the transistor. It controls the number of charge carriers that pass from the emitter to the collector.
7. What is Collector in Transistor?
The collector is the terminal that collects charge carriers from the emitter through the base. It is moderately doped and larger to dissipate heat generated during operation.
8. Why Collector region is wider than Base and Emitter?
The collector region is made wider to handle more heat and collect more charge carriers, ensuring efficient operation and preventing damage during high current flow.
9. What is the meaning of Transistor?
The word transistor comes from “transfer + resistor.” It means a device that transfers a weak signal from low resistance to high resistance, thus amplifying the signal.
10. Why Transistor used as an Amplifier?
A transistor is used as an amplifier because it can boost weak input signals by controlling a large output current with a small input current at the base terminal.
