FAQs on Transistor as an Amplifier Video Lecture - NEET

1. What is a transistor amplifier?
Ans. A transistor amplifier is a device that uses a transistor to increase the amplitude of an electrical signal. It takes a weak input signal and produces a larger output signal, thereby amplifying the signal.
2. How does a transistor amplifier work?
Ans. A transistor amplifier works by using the properties of a transistor to control the flow of current between its terminals. By applying a small input signal to the base terminal of the transistor, it modulates the current flowing through the transistor, resulting in an amplified output signal at the collector terminal.
3. What are the advantages of using a transistor amplifier?
Ans. Transistor amplifiers offer several advantages, including high gain, low power consumption, and compact size. They also provide stability, reliability, and can be easily integrated into electronic circuits.
4. Can a transistor amplifier amplify both AC and DC signals?
Ans. Yes, a transistor amplifier can amplify both AC (alternating current) and DC (direct current) signals. However, it is important to note that the amplification of DC signals requires specific biasing techniques to avoid distortion and saturation of the transistor.
5. What are the different types of transistor amplifiers?
Ans. There are several types of transistor amplifiers, including common emitter, common base, and common collector configurations. Each configuration has its own advantages and is suitable for different applications.
