Potentiometer Wiring Schematic

Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker.

Potentiometer wiring schematic. Some guitar wiring circuit designs use 300k or even 1 meg pots. 500k vs 250k tone pots. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. This material creates resistance.

Begin constructing the schematic on the left by first connecting the battery holder not shown to the breadboard. We call the middle pin the wiper. Connect end 1 of the potentiometer to the voltage source and attach the wiper terminal 2 to ground. They can provide a variable resistance by simply varying the knob on top of its head.

It is connected somewhere on the strip between the two ends. In the exercise below you will practice wiring the variable resistor in different ways in a series circuit. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. One is their resistance r ohms itself and the other is its power p watts rating.

Full size pot shafts usually have fine splines needing 3 8 round mounting holes. It has three pins and the schematic symbol looks like this. The terminal 2 is connected to the wiper. Between the two side pins of the potentiometer there is a strip of resistive material.

Here s what you need to know about choosing the right pots for your guitar. Potentiometers also known as pot are nothing but variable resistors. How to wire a potentiometer. Both 250k pots and 500k pots have their place in making a guitar sound great.
