Reasons Why the World Would Not Run Without the Use of Custom Resistors
Undoubtedly, the world wouldn’t be as liveable as it is now if electricity wasn’t invented. We cant imagine a world today that is devoid of the results of the innovation of electricity such a lighting, heating or running of industrial plants. Electrical energy flows in a circuit by the use of conductors. From time to time, it may be needful to block this flow of electrical energy to achieve certain results. Circuital components that can be used to achieve this goal are 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. In normal circumstances, we have two categories of resistors – the fixed as well as the variable valued resistors. In variable valued resistors, the amount of resistance that is obtained from these components can be increased or decreased according to the needs of a circuit. By varying the amount of the resistance in a connection, the outputs of a circuit may be varied to give higher or lower outputs. An example of this is seen in the controlling of the sound amplifier.
The second use of custom resistors is to achieve heating. 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. This heat is one of the many ways that electric bulbs use to generate light. One of the commonest applications of this mechanism is also seen in electrical heating devices.
More than that, resistors are also useful in the formation of what is called voltage division in an electrical circuit. For this to be achieved, a good number of resistors need to be wired together in series to form a daisy chain. 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. When the values differ, the voltage will also vary. The aim of such a connection is to ensure that what was produced at the mains is subdivided into smaller amounts of voltages that can be consumed by appliances with lower power specifications.
Lastly, resistors are also needed for the functioning of LEDs and transistors. 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. 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.
