What is a Fixed Resistor? A fixed resistor is one of the most common types of resistors used in electronic circuits. It is a passive component that has a fixed resistance value, which means that its resistance does not change with changes in temperature or voltage.
Fixed resistors are used to limit the flow of electric current in a circuit, and they come in various shapes and sizes depending on their intended use. They can be made from different materials, such as carbon, metal film, or wire-wound materials, each with its own unique properties.
The resistance value of a fixed resistor is measured in ohms (Ω), and it can range from just a few ohms to several megaohms. The exact value of the resistance is indicated by color codes or numerical markings printed on the body of the resistor.
Types of Fixed Resistors
There are several types of fixed resistors available on the market, including:
- Carbon composition resistors
- Metal film resistors
- Wire-wound resistors
- Thick film resistors
Each type has its own advantages and disadvantages depending on the intended application.
Applications of Fixed Resistors
Fixed resistors are used in a wide range of electronic devices and circuits, including:
- Power supplies
- Voltage regulators
They play an important role in regulating the flow of electrical current through these devices and ensuring that they operate safely and efficiently.
So if your question was What is a Fixed Resistor? Fixed resistors are essential components in electronic circuits that help regulate the flow of electrical current. By understanding how they work and their applications, you can design more effective circuits for your projects.
