Uses of Custom Resistors

There are instances when a given amount of electric current needs to be controlled for various reasons. As a result, the best way to do so is by use of resistors. This is because resistors have been made in such a way that they can control the amount of current passing through them and the end result is heat that ends up being produced by the resistor. Electric flow is usually slowed down because a resistor is build in such a way that electrons end up colliding with ions thus reducing current flow. Resistors have various uses as listed below.

The first use of resistors is in timing and frequency. When a custom resistor is attached to a capacitor in any circuit design, it acts as a tool to create a perfect timer. This has been illustrated in like signs, electronic sirens and in light flashers. It usually takes time to fill a capacitor with charge just like how it takes time to fill up a cup with water. The time taken to fill up the charge in a capacitor acts as a timer.

Another great us resistor is in transistors and LEDs. This is because these two are quite sensitive to flow of electric current and as such, if too much current was passed through them, they would end up getting destroyed. At the same time, too little current would also limit their ability to work as expected. If one has a resistor that has the right value, basically with the ability to keep current flowing in an even manner, it becomes easy to have LEDs and transistors working.

It is also the work of resistors to heat. This is because when electric current flows through them, they end up producing heat. This heat can be used in equipment such as toasters, water heaters among others similar gadgets. Such gadgets happen to require high temperature to pass through them and with a resistor of the right value, it becomes easy to achieve this.

It is also possible to use resistors to divide voltage. This is because there are gadgets that may not require too much voltage for them to work. With the right resistor, this becomes quite easy to achieve because an input may supply more voltage than that required by a device. For that reason, a resistor comes in handy. Too much voltage can be divided by connecting a series of resistors.
