Potentiometer Wiring Schematic

Some guitar wiring circuit designs use 300k or even 1 meg pots. They can provide a variable resistance by simply varying the knob on top of its head. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3.

How to wire a potentiometer.

Potentiometer wiring schematic. Here s what you need to know about choosing the right pots for your guitar. One is their resistance r ohms itself and the other is its power p watts rating. They have a small shaft on top that functions like a knob. For example as carbon.

Potentiometers also known as pot are nothing but variable resistors. Between the two side pins of the potentiometer there is a strip of resistive material. Connect end 1 of the potentiometer to the voltage source and attach the wiper terminal 2 to ground. Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker.

It can be classified based on two main parameters. We call the middle pin the wiper. 500k vs 250k tone pots. Begin constructing the schematic on the left by first connecting the battery holder not shown to the breadboard.

It is connected somewhere on the strip between the two ends. This material creates resistance. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. The terminal 2 is connected to the wiper.

In the exercise below you will practice wiring the variable resistor in different ways in a series circuit. Both 250k pots and 500k pots have their place in making a guitar sound great. 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.
