Top Four Applications of Custom Resistors Today
electrical energy has such an important role in ensuring that the world is habitable. It would be almost impossible to live this earth without for example having all the results of electrical energy such as heating, lighting, the powering of industrial units among many others. Electrical energy flows in a circuit by the use of conductors. More often than not, there is of a necessity a need to inhibit the free flow of electricity through conductors so that certain results can be obtained. However, to achieve this, there is a need for circuital components called resistors. What then do resistors accomplish when they are wired in any circuit?
The first important use of custom resistors and where they may be needed is where they can be used as elements for controlling results of certain connections. In normal circumstances, we have two categories of resistors – the fixed as well as the variable valued resistors. According to the needs of an electrical circuit, you will find that varying valued resistors can have their resistance increased or decreased accordingly. By varying the amount of the resistance in a connection, the outputs of a circuit may be varied to give higher or lower outputs. The sound amplifier, for instance, makes use of this application.
Secondly, heating using electricity would be impossible without the use of resistors. Normally, resistance to the flow of electricity is a process that produces a lot of heat. Electricity can thus be converted into heat by the use of resistors. The heat produced is important for producing light- where bulbs make use of the heat to give light through there filaments. The heat from resistors can also be found in electric heaters and many other heating devices.
Custom resistors can also be employed to serve as voltage dividers in electrical circuits. A voltage divider is essentially created when a chain of custom resistors are joined in a series connection to form a daisy chain. You will realize that if the resistors used for this purpose in a single circuit have an equal value, the amount of voltage across them is also equal. However, when the values are different, the voltages will also differ. In the end, various values of voltages are produced for the same connection despite the fact that the mains voltage is higher than the voltage at the resistors.
Lastly, resistors are also a necessary component for transistors and LEDs to function. The LEDs and transistors are usually not able to work in the event where too much or too low amounts of electric current is passed to them. Due to this, the devices can only work when resistors of the right value are used together with them.
