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. In order to regulate the number of electrons flowing in a circuit, it is key to employ some resistance via the use of electronic devices known as resistors. Following our below discussion, you will find out that the applications for these electrical devices are really numerous.
Timers can be used for a number of real-life use cases but they cannot be created without using resistors. In this regard, the resistor has to be wired together with a capacitor so that it can serve the purpose of a timer. Car sirens, flashers as well as many other devices make use of these timers. The timing mechanism works by allowing charge to fill in a capacitor only bit by bit as is permitted by the resistor that is connected to it.
by understanding the simple fact that capacitors store electric charge, you will appreciate the fact that we can determine the time that is needed to fill a capacitor with charge by using the resistors. 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. By passing the voltage through a number of resistors of equal or varying resistance the voltage across these resistors ends up being divided. This is usually important when it is required that an appliance that has a low intake of voltage has to be connected in a circuit that is powered from the mains. 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. Resistors connected in this manner for purposes of causing voltage differences in an electric circuit are said to form a daisy chain of resistor connection. Daisy chains can be used in a number of applications.
