They are used in electronic circuits to filter out noise, smooth out voltage fluctuations, and store energy.
Diodes:
Diodes are components used to allow electrical current to flow in one direction only. They are made of semiconductor material, such as silicon or germanium. When current flows through a diode, it can only flow in one direction. Diodes come in different shapes and sizes, with the most common being the cylindrical shape with two leads. They are used in electronic circuits as rectifiers, voltage regulators, and signal limiters.
Transistors:
Transistors are components used to amplify or switch electrical signals. They are made of semiconductor material, such as silicon or germanium. There are two main types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs). BJTs are used to amplify signals, while FETs are used to switch signals. Transistors come in different shapes and sizes, with the most common being the cylindrical shape with three leads. They are used in electronic circuits as amplifiers, switches, and oscillators.
Integrated Circuits:
Integrated circuits (ICs) are components used to create complex electronic devices, such as computers and smartphones. They are made of semiconductor material and consist of multiple components, such as transistors, resistors, capacitors, and diodes, on a single chip. ICs come in different sizes and shapes, with the most common being the square or rectangular shape with pins on the sides. They are used in electronic circuits to perform complex functions, such as logic gates, memory storage, and signal processing.
