FAQs on What is Transistor? Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)

1. What is a transistor?

Ans. A transistor is a semiconductor device that can amplify or switch electronic signals and electrical power. It is the fundamental building block of modern electronic devices and is commonly used in applications such as radios, televisions, computers, and mobile phones.

2. How does a transistor work?

Ans. A transistor consists of three layers of semiconductor material, typically made of silicon. These layers are called the emitter, base, and collector. By applying a small current or voltage to the base, the transistor can control a larger current flowing between the emitter and collector. This control allows the transistor to amplify or switch electronic signals.

3. What are the types of transistors?

Ans. There are two main types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs). BJTs consist of two PN junctions and are further classified into NPN and PNP transistors. FETs, on the other hand, are categorized into junction field-effect transistors (JFETs) and metal-oxide-semiconductor field-effect transistors (MOSFETs).

4. What are the advantages of using transistors?

Ans. Transistors offer several advantages over other electronic components. They can amplify weak electrical signals, allowing for efficient signal processing. Transistors are also compact in size, consume less power, and have faster switching speeds. Additionally, they are more durable and reliable compared to older vacuum tube technology.

5. What is the significance of transistors in modern technology?

Ans. Transistors have revolutionized modern technology by enabling the development of smaller, more efficient, and powerful electronic devices. They are essential components in computers, televisions, radios, smartphones, and many other electronic systems. Transistors have paved the way for advancements in communication, computing, and automation, greatly impacting various industries and improving our daily lives.
