A chip resistor is a small electronic component used to control the flow of electric current in a circuit. These resistors are typically made from a ceramic material and are designed to be mounted directly onto a circuit board. Their compact size allows for efficient use of space in electronic devices, making them popular in modern technology. Chip resistors come in various resistance values and power ratings, allowing engineers to select the appropriate type for their specific applications. They are commonly found in devices such as smartphones, computers, and automobiles, where precise control of electrical signals is essential for proper functionality.
