Top Four Applications of Custom Resistors Today
Undoubtedly, the world wouldn’t be as liveable as it is now if electricity wasn’t invented. 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. A conductor is necessary if an electric current were to flow in a circuit. For certain results to be obtained at times, it is imperative that this flow of electrical energy through conductors is impaired somewhat. Blocking of the flow of electrical energy in circuits requires the use of circuital components commonly known as resistors. What then are the uses of resistors in an electrical circuit?
One of the most important applications of resistors is in the aid of enforcing controls of certain circuits so that the results of those circuits can be determined. Normally, resistors are categorized into two- the fixed value and the varying 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.
The second use of custom resistors is to achieve heating. The process of electric resistance is one that is capable of producing a lot of heat. Resistance can thus be viewed as a way to transform electrical energy into heat. This heat is one of the many ways that electric bulbs use to generate light. The heat in electrical heaters is also generated in this way.
Custom resistors can also be employed to serve as voltage dividers in electrical circuits. For this to happen, a number of resistors need to be wired together in a series circuit. 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. When the values differ, the voltage will also vary. 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. These components are usually affected by either too low or too high amounts of electricity passing through them. Owing to this fact, they have to be wired with the right resistor with the right amount of resistance that will allow only limited amount of electric current to flow through them in order for them to work and to continue working.
