This is Why You Need Custom Resistors

electrical energy has such an important role in ensuring that the world is habitable. 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. 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. However, to achieve this, there is a need for circuital components called resistors. What then are the uses of resistors in an electrical circuit?

First and foremost, custom resistors can be necessary for the control the outputs that are generated in certain electrical circuits. Generally, resistors can be classified as being fixed or of variable values. According to the needs of an electrical circuit, you will find that varying valued resistors can have their resistance increased or decreased accordingly. Accordingly, the outputs of the circuit are affected based on the variations set on the amount of resistance. The sound amplifier, for instance, makes use of this application.

The second thing to note is that custom resistors can also be employed for heating purposes. In normal cases, resistors work by generating 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. The heat in electrical heaters is also generated in this way.

The other interesting application of custom resistors is where they may be used as voltage dividers in electrical connections. A voltage divider is essentially created when a chain of custom resistors are joined in a series connection to form a daisy chain. The implication for this is that when the chain is formed from resistors of the same value, the voltage across them is also equal. The voltages will differ, however, if the resistors are different. 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. 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.
