Passives are electronic components that do not require a power source to operate. They are used in a wide range of electronic devices and systems, including computers, televisions, radios, and mobile phones. Passives are essential components in electronic circuits, and they play a critical role in the functioning of these circuits. In this article, we will discuss the various components and modules that make up passives.
Resistors
Resistors are one of the most common types of passive components. They are used to limit the flow of current in a circuit. Resistors are made of materials that resist the flow of electricity, such as carbon, metal, or ceramic. The resistance of a resistor is measured in ohms (Ω), and it determines how much current can flow through the circuit. Resistors are used in a wide range of applications, including voltage dividers, current limiters, and signal conditioning circuits.
Capacitors
Capacitors are another essential component of passive circuits. They are used to store electrical energy and release it when needed. Capacitors are made of two conductive plates separated by a dielectric material. The capacitance of a capacitor is measured in farads (F), and it determines how much charge the capacitor can store. Capacitors are used in a wide range of applications, including power supplies, filters, and timing circuits.
Inductors
Inductors are passive components that store energy in a magnetic field. They are made of a coil of wire wrapped around a core material, such as iron or ferrite. The inductance of an inductor is measured in henries (H), and it determines how much energy the inductor can store. Inductors are used in a wide range of applications, including filters, oscillators, and transformers.
Transformers
Transformers are passive components that are used to transfer electrical energy from one circuit to another. They are made of two coils of wire wrapped around a core material, such as iron or ferrite. The primary coil is connected to the input circuit, and the secondary coil is connected to the output circuit. Transformers are used in a wide range of applications, including power supplies, audio amplifiers, and radio receivers.
Diodes
Diodes are passive components that allow current to flow in only one direction. They are made of a semiconductor material, such as silicon or germanium. When a voltage is applied to a diode, it allows current to flow in one direction but blocks it in the other direction. Diodes are used in a wide range of applications, including rectifiers, voltage regulators, and signal detectors.
Transistors
Transistors are passive components that are used to amplify or switch electronic signals. They are made of a semiconductor material, such as silicon or germanium. Transistors have three terminals: the emitter, the base, and the collector. When a voltage is applied to the base terminal, it controls the flow of current between the emitter and the collector terminals. Transistors are used in a wide range of applications, including amplifiers, switches, and oscillators.
Integrated Circuits
Integrated circuits (ICs) are passive components that contain multiple electronic components on a single chip. They are made of a semiconductor material, such as silicon. ICs can contain a wide range of components, including resistors, capacitors, diodes, and transistors. ICs are used in a wide range of applications, including microprocessors, memory chips, and digital signal processors.
Conclusion
Passives are essential components in electronic circuits, and they play a critical role in the functioning of these circuits. The components and modules that make up passives include resistors, capacitors, inductors, transformers, diodes, transistors, and integrated circuits. Each of these components has its own unique properties and applications, and they are used in a wide range of electronic devices and systems. Understanding the components and modules that make up passives is essential for anyone working in the field of electronics.
