If the maximum dissipation is 05w and the resistance is 10k then the maximum current that may flow through the entire resistance element is. Wiring illustration for using a potentiometer as a rheostat.
Awesome Wiring Diagram Potentiometer Diagrams Digramssample
Potentiometer wiring diagram. Assuming series or two terminal rheostat wiring. They have a small shaft on top that functions like a knob. The diagram shows the parts present inside a potentiometer. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. Lets look at the 05w pot and 10k is a good value to start with for explanation. How to wire a potentiometer.
We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot. Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker. The standard schematic symbol for a pot is shown to the left. If you need a simple resistor that you can change the resistance of you only need two pins. Ohms law schematic diagram. The terminal 2 is connected to the wiper.
The middle pin and one of the side pins. Keep that in mind and have a look at the following three examples on how to wire a potentiometer. Instructions for potentiometer wiring. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. The above image shows a simple circuit to dim an led. For this experiment you will need a relatively low value potentiometer certainly not more than 5 kω.
Lessons in electric circuits volume 1 chapter 2. As the symbol suggests a potentiometer is nothing but a resistor with one variable end.
