Basic Knowledge On How A Voltage Divider Works

By Melissa Williams


Working with music or a recorder may impose a lot of concerns specifically on its volumes. For example, when doing a voice over, your recorded audio may be overpowered by a background music. To settle the needs for this adjustment, you should have a device that is deemed as a variable resistor. This device may also be applicable if you would like to take measurements for deflections on performing centers or when you wish to reduce the noise you are experiencing in your motorbike.

In some cases, devices which involve circuitry and an equation are produced as an aid to these situations. Known as the most fundamental circuit, this tool is called a Voltage Divider. It is a passive circuit which helps reduce the large volumes of your audio equipment or other electronics.

With three variables namely two resistors and an initial voltage, you can already turn a large Volt count into a smaller one which is considered as the output Volt. To simplify this, you could understand the process better using a certain equation. This equation is basically a representation of the Ohms law which observes a direct proportion relationship between a current and the difference of ends. Having said so, it is understood that as the current is reduced by the attached divider in between two resistances, the voltage released is also lowered.

This divider has two main parts namely the circuit and the equation. To make it work, first, you should secure a circuit by putting in two resistors together. The equation, on one hand, allows you to calculate the output after you have found the ratio of both resistors while considering the input volt as another variable.

You can also create your own device if you wish to but you have to be mindful that when creating your portable gear. Most simple electronics can only withstand 5V, however, most sources like for example your remote control, a standard 9V battery will do. To do so, first, you should prepare the specific tools needed such as your leads, resistors, your battery, three alligator clamps, connectors and your voltmeter.

Begin by connecting the leads with an alligator clamp. One should contain the red lead resistor with 10 Ohms and the other should contain the black one which has 20 ohms. Then after connecting these leads, use the free end to twist these two together.

Putting together the two leads. Twist together both lead ends and lock it up using the last alligator clamp. After doing so, take the connector of your voltmeters then do the correct terminal placing. Red wires go to the positive terminal of your battery while the black wires refer to the negative one. Then you can start turning your meter on.

As you can see from 9V, your voltage goes down to 3V. When this happens, the positive terminal of the circuit is now the one where the twist is located. Meanwhile, the negative terminal is retained as the negative source.

Before going through this procedure, unhook the end of the divider. In some case, you have to unplug your battery to avoid draining. For this procedure, your 9V energy source does not really show a lot of danger. But, when working with some other electronics, make sure to unplug the wires from wall outlets as this may cause electrocution.
