All electrical devices need power resistors for them to operate their best. You can use them for much simpler applications with the likes of power supplies. On the other hand, you can also use them for more complicated applications with the likes of some military systems like sonars and radars. Power resistors can be obtained from a number of resources. Nonetheless, you should put some careful thought when you will be buying your own power resistors. To choose the right power resistors for whatever application you have in mind, you have to take note of a few factors first, and some of them will be made mention here. Here are some important reminders in choosing power resistors. Make yourself one of the luckiest person who learn about the current shunt resistor company.
Before getting your hands on any power resistors, you have to be well aware of the basic law of electricity. This is the Ohms law to help you better decide which power resistor you should be getting. According to Ohms law, the current that is flowing in the resistor is directly and inversely proportional to the voltage and resistance that you will find across it, respectively. This current that flows through your power resistor is capable of producing heat. This is what you call the heat dissipation process. Thus, when looking for power resistors, you have to consider heat dissipation.
Going back to heat dissipation, this is another factor that you have to consider when you look for power resistors. While looking for possible power resistors that you can purchase and use for whatever application you have in mind, you have to find one that can withstand the heat that your device or equipment will be generating. While withstanding this heat, they should be able to retain their performance as well as functionality. Basically, no physical damage or performance reduction should take place. Keep in mind that you can expect power resistors to rise in temperature because of the electric current that you find going through the power resistor. Again, you have to be particular in choosing a power resistor that is capable of dissipating heat. Furthermore, you have to find a power resistor that can withstand any temperature increases that your device will encounter. Be more curious about the information that we will give about custom wirewound resistor.
Lastly, the physical size and construction of your power resistor are two other things that you have to take into careful account. The both of these factors are telling if heat can be dissipated or withstood through them. You have to be familiar with this associated concepts and factors of power resistors before you go about choosing one. Only then can you be sure that what you have chosen is really suitable to the application you have in mind.
