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. It is very imperative that we come to the understanding of some of the basics in electricity for us to better understand the uses of resistors.
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. For purposes of regulating the flow of these electrons in a circuit, it is important that you use devices known as resistors. 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 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.
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 energy that is stored in a capacitor is only released once the capacitor is full and this completes the cycle of the timing mechanism. 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 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. 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. Resistor connection of this kind is what is called a daisy chain. These daisy chains have been applied in different electrical appliances.
