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.
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.
Using two resistors, this divider shall allow you to turn a large voltage into a smaller one provided that you also have the value of input voltage. Understand how this device works need you to be familiar with the Ohms law which states, the direct current flowing in a conductor is directly proportional to the potential difference between its ends.
There are two essential parts of this divider, one is the circuit and the other is the equation. The circuit pertains to a source of the Volt which goes across two resistors. For the equation, you have to assume three values namely input voltage, resistor one R1, and resistor two R2. The output value could be found by taking the ratio between R1 and R2.
Though you can buy your own device, creating a portable one can be a better choice as it helps you save. For this, you have to secure leads, resistors, a 9V battery, alligator clamps, voltmeter and its connectors. In addition, you have to ensure that you get at most the standard battery voltage which is 9.
Connect leads to its proper colors. Using an alligator clamp, find the red lead of your battery and attach the clamp. Following the same pattern, do the process toward the black lead of your energy source.
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.
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.
When doing this procedure, always see to it that you have unhooked an end of a divider or unplugged your battery to prevent it from draining. More so, be cautious when working with these types of wiring especially the ones which are still plugged into its outlet because it may result in electrocution. In this case, however, there is not much danger in a 9V energy source.
