What You Need To Take Note When Looking For Power Resistors
There are a number of applications that would make use of power resistors. Among the most common use of these power resistors are the simple ones like the power supplies to the more complex ones like the sonar and radar, and many more military systems. Even if you will easily find a power resistor that will be perfect for all your needs and applications, you need to always take note on a number of important things every time you will be looking for the right power resistor. This article will be able to learn some of the things that you should consider when it comes to looking for a power resistor.
You need to know first the Ohms law, which is the basic law of electricity before you will choose a power resistor. The Ohms law explains how the current that will go through the resistor as inversely proportional to the resistance, it is also directly proportional to the voltage that you will find across it. Heat can be produced by the electric current that will flow through the power resistor. Another important factor that you should take note of every time you will be looking for a power resistor is the idea of heat dissipation.
There is one important thing that you need to know first every time you will be looking for a power resistor for your needs. Every time you will be looking for a power resistor, you will need to choose one that will be able to endure the heat that it will generate without having any deterioration or physical damage. There will be a rise in the temperature of the power resistor because of the electric current that will flow through the power resistor. You must look for a resistor that will be able to dissipate the heat. It is also important for you to choose a power resistor that will be able to endure the rise in temperature that it will experience.
The construction and physical size of the power resistors will affect its ability to withstand and dissipate heat. You should always take note of this as well as the other important features of the power resistor that you will be choosing. You need to know first what is its require resistance value. Next is you should know that the watts must also be dissipated by the power resistor that you will choose. You will also need to take note of the physical size that will be required by the mounting and environmental conditions, maximum temperature, watts dissipation, and the volts. And lastly, you will need to make sure that the power resistor is properly constructed. You need to make sure that you will take note of all these factors in order for you to really choose the best power resistor.
