Greetings
Can somebody please help me understand the use of transistor as a switch and that as an amplifier?

dionysian said:And if they can only be used to amplifier small signals what is that point of that? Do most of the applications in which we need signal amplifaction pretain only to small signals?
The main purpose of a transistor is to amplify and switch electronic signals. It can be used to control the flow of electricity in a circuit, making it an essential component in many electronic devices.
A transistor is made up of three layers of semiconductor material, typically silicon. By applying a small voltage to the middle layer, called the base, the transistor can control the flow of current between the other two layers, known as the emitter and collector. This allows the transistor to amplify or switch electronic signals.
Transistors are used in a wide range of electronic devices, including computers, televisions, radios, and smartphones. They are also commonly used in power supplies, amplifiers, and digital circuits.
Yes, transistors can be used in alternative energy sources such as solar panels and wind turbines. They are used to convert and regulate the electricity generated by these sources, making them more efficient and usable.
Transistors have greatly impacted technology by making electronic devices smaller, faster, and more efficient. They have also made devices more affordable, as transistors are cheaper to produce than their predecessor, vacuum tubes. Transistors have played a crucial role in the development of modern technology, from computers to smartphones to medical equipment.
