How To Create Your Portable Voltage Divider

By Melissa Williams


When you are designing a piece of audio equipment, one of your major concerns is how you get to regulate or control its volume. In this case, a potentiometer which is a variable resistor may be used for specific adjustments. The device used in this situation helps you gain controls for any variable.

With an understanding of how circuitry and an equation works, you can make use of a device that could help regulate the voltage amount of the audio equipment or other electronics. A voltage divider is a passive type of line that produces an output value. This value is the lowered amount of initial voltage.

The Ohms law is used to understand the result of this device. It states that current flowing in a conductor is proportional to the difference between its ends. Meaning, if the current is reduced, then the Volt is also reduced.

A circuit where the Volt runs through is one of the essential parts of this tool. The other is called an equation where you should find the Vout by taking the ratio between two resistors. These two parts are vital in reducing your volt counts and in the absence of either one of its variables, the procedure will never take effect.

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.

Start by connecting one lead to a red lead of a 9V battery with an alligator clamp. Then using another lead, do the same steps but this time using the black lead of the connector. After, you can twist the free end of each resistor together.

Make sure that you have provided a solid twist for it by clamping an alligator clamp on it. Then look at the positive and negative terminals of the battery. When found, attach the red wire to the positive and the black wire to the negative. Then turn your meter on.

The positive voltage terminal of your circuit would be the connector which holds the twisted resistors together in place. On one hand, the negative terminal retains to be the negative source. Using the given equation, the new Volt count of your 9V battery goes down to 3V.

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.
