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.

This type of circuitry is of great aid when wanting to divide volumes of voltages sent. To simplify, the specific device that you should have is called a voltage divider. This happens to be one of the most fundamental circuits you will be dealing with in the field of electronics.

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.

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.

Over the twisted leads, ensure a solid twist by clamping the last alligator clamp on it. Then using another connector, place the red wire on the positive terminal of the battery and place the black one in the negative terminal. Hold similar charges together of positives and negatives of your voltmeter lead and clamps and turn your meters 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.

Creating your own portable device is just easy. However, you have to take safety measures for this. When dealing with a 9V battery, however, you may not see a lot of danger for it in terms of electrocution possibilities. But for other electronics, make sure that you have unplugged the wires before working on it.
