Undoubtedly, the world wouldn’t be as liveable as it is now if electricity wasn’t invented. Important results of the innovation of electricity such as lighting and heating have all made the world as much livable as possible. Electrical energy flows in a circuit by the use of conductors. For certain results to be obtained at times, it is imperative that this flow of electrical energy through conductors is impaired somewhat. 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?
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. Generally, resistors can be classified as being fixed or of variable values. The variable resistors are those whose values of resistance can be changed to achieve varying amounts of electrical resistance. 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. Resistance can thus be viewed as a way to transform electrical energy into heat. This heat that is converted in this way is first of all seen in electric bulbs which are used for lighting our premises. 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. This application works on the premise that if all the resistors in a chain are of the same value, then the amount of voltage at each resistor will be equal. The voltages will differ, however, if the resistors are different. 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.
Finally, LEDs and transistors won’t work if there were no resistors. These two components will never function in the event where there is too high or too low amounts of electrical currencies passed through them. In order that these two components can work and continue to work, it is imperative that resistors are wired with them to allow only the amount of currents that they can tolerate.
