Top Four Uses of Custom Resistors That You Should Know
The use of custom resistors in our day to day lives is something that we must be aware of. It thus goes without saying that we literally cannot do anything without the use custom resistors. Before we can look into those uses, it is important that we establish certain concepts in electricity since this is important for our understanding of the different uses of custom resistors.
The unidirectional flow of electricity via a conductor is what gives rise to an electric current. Electrons are the fundamental building blocks of electric energy. Electrical devices known as resistors are important when there is a need to regulate the amount of electricity flowing in a circuit by the use of resistance. The applications for these devices are multifaceted as we shall discuss below.
Firstly, these components are useful for coming up with a timing mechanism that can be employed in a number of devices. For resistors to work in this way, they have to be connected together with capacitors. The many day to day uses of lighting flashers, auto sirens and many other timing mechanisms rely on this mechanism. For timing to occur, the underlying factor is that the capacitor must be filled with some amount of charge which is regulated by the capacitor.
Capacitors are made to hold electric charge thus by regulating the amount of electricity that goes into them using custom resistors, we can decide the time that is needed to feel a given capacitor with electric charge. The cycle of the timing mechanism is only completed when the capacitor is filled with charge at which time it releases the energy to prepare for the next cycle of timing. The cycles are repeated sequentially depending on the amount of electricity that is permitted through a resistor.
Resistors have also been employed over time to serve the purpose of dividing the amount of voltage that is dissipated at certain junctions in a circuit. The voltage in this regard is divided when it is passed through resistors of either equal or different values of resistance. The need for this is to ensure that appliances that cannot directly be connected to the main owing to their low power ratings are powered. This very concept can be used in any instance where there is a need to produce varying amounts of power by considering a careful tradeoff between the amount of electric current flowing and the resistance that is applied to such an electrical circuit. Resistor connection of this kind is what is called a daisy chain. Various electrical appliance employ this concept of daisy chain connection.
