Things That You Need To Know About Choosing Power Resistors
There are so many different applications that are using power resistors. The most common use of these power resistors are on those simple ones like the power supplies, and the complicated ones such as the radar and sonar, and some other military systems. Even if you will be able to find a power resistor easily that will suit your needs and uses, you still need to keep in mind that there are so many important things that you should consider every time you will look for a 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.
It is important for you to know first the basic law of electricity which is the Ohms law before you will decide on 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. The electric current that will flow through the power resistor will be able to produce heat. Heat dissipation is another thing that you need to take note of every time you will be choosing a power resistor.
There is one important thing that you need to know first every time you will be looking for a power resistor for your needs. When it comes to looking for a power resistor, you will need to look for one that will be able to endure the heat it will generate without causing any performance reduction and physical damage. The electric current that will be flowing through the power resistor will be able to produce a rise in temperature. The power resistor that you will find should be able to dissipate 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 need to take note of this and all the important features of the power resistor that you will choose. You should know how much is the resistance value required by the power resistor. 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. The last thing that you need to do is to look for a power resistor that has the best construction. You need to take note on all of these things in order for you to really find the right power resistor for all your applications and uses.
