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. Owing to this fact, it can be said that custom resistors are indispensable in our daily lives. 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. 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.
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. For resistors to work in this way, they have to be connected together with capacitors. Car sirens, flashers as well as many other devices make use of these timers. The working of this times relies on how fast the capacitor is filled with electric charge and this is determined 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. 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 energy is released at intervals whose timing is controlled by the resistance that is applied to the circuit.
Finally, to ensure that there is the division of voltage that is dissipated across the components of an electrical circuit, it is imperative that there is the use of custom resistors. By passing the voltage through a number of resistors of equal or varying resistance the voltage across these resistors ends up being divided. 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. Daisy chains can be used in a number of applications.
