rezistoriai

Rezistoriai, also known as resistors, are passive electrical components that are used to limit or regulate the flow of electrical current in an electronic circuit. They are typically made from materials with high electrical resistance, such as carbon, metal alloys, or semiconductors. Resistors are characterized by their resistance value, which is measured in ohms (Ω) and is usually indicated by colored bands or a numerical code on the resistor body.

The primary function of a resistor is to dissipate electrical energy as heat, which is why they are often used in power dissipation applications. They can also be used to set voltage levels, divide voltages, and bias transistors in electronic circuits. Resistors are available in various sizes, shapes, and power ratings, ranging from small surface-mount devices to large axial-lead components.

Rezistoriai are essential components in electronic circuits, and their proper selection and application are crucial for the performance and reliability of the circuit. They are widely used in a variety of applications, including power supplies, signal conditioning, and control systems. The use of resistors in electronic circuits dates back to the early days of electrical engineering, and they continue to be an important and fundamental component in modern electronics.
