What Is a Power Resistor?
A power resistor is designed to manage power within electrical circuits.
While functioning like standard resistors in limiting current flow, power resistors are specifically designed for high power and voltage applications. They are critical in circuits of electronic devices where controlling or converting power efficiently is essential.
Equipped with robust structures, such as thick resistance materials or cooling fins, power resistors excel in handling significantly more power and voltage than their regular counterparts. This capability makes them indispensable in high-power equipment like power supplies, motor controls, and generators. Their main function is to fine-tune power delivery, safeguarding circuit components from potential damage due to excess power or voltage.
