Not laughing at you, just recognizing that feeling.rachmaninoff said:It's not nice if you laugh.
Ask someone that knows you very well, that is not related. There inlays the true answer.blimkie said:
Power resistors are often used in high-power applications, such as industrial machinery and power supplies, where they are required to dissipate large amounts of heat. As a result, they need to be physically larger and have a higher power rating compared to standard resistors. This makes them less common and harder to find.
Yes, there are alternatives such as wirewound resistors, metal oxide film resistors, and thick film resistors which can handle higher power ratings. However, they may not be suitable for all applications and may have different characteristics compared to power resistors.
Technically, yes, you can use multiple standard resistors in series or parallel to achieve a higher power rating. However, this can be more complex and may not be as efficient as using a single power resistor. It is important to carefully calculate and consider the power dissipation requirements for your specific application.
Power resistors are larger and have a higher power rating, which requires more materials and manufacturing processes. Additionally, they may also need to be custom-made for specific applications, which can increase the cost. The demand for power resistors is also lower compared to standard resistors, making them less economically feasible for manufacturers to produce in large quantities.
No, it is not recommended to use a lower power rated resistor in place of a power resistor. Power resistors are specifically designed to handle higher power dissipation, and using a lower power rated resistor can lead to overheating and potential failure. It is important to use the appropriate components for your specific application to ensure safety and reliability.
