Top Four Uses of Custom Resistors That You Should Know
Custom resistors have a broad range of use in our day to day lives and we all must be aware of this. It thus goes without saying that we literally cannot do anything without the use custom resistors. For better understanding of the applications of resistors, it is key to understand certain fundamental concepts about electricity.
Electrical energy is generated when there is a flow of electric current through a conductor that is wired in a circuit. This current is made up of electrons. 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.
The first application of resistors is where they are used in circuits to form the timing mechanism that can be used in a number of cases. In this regard, the resistor has to be wired together with a capacitor so that it can serve the purpose of a timer. 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.
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. Once the capacitor is filled with charge, then a burst of energy is released and this forms the timing mechanism such as is used in a car siren. 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. This phenomenon is significant in the event that an appliance that is being connected to the voltage source cannot consume a given amount of voltage due to the fact that its input specifications are lower than that generated by the mains. Further to that, in any application where lower voltages are needed, the concept of voltage division can be implemented by ensuring that current flows in a circuit are varied depending on the varying amounts of resistance applied to those circuits. When resistors are used in this pattern to cause voltage division, they are said to be connected in a daisy chain. These daisy chains have been applied in different electrical appliances.
