→Common Ground
Ground (sometimes called neutral or earth) is usually at 0V. Ground acts a reference point for most electronic circuits. It is good practice to connect all ground references to a common point; inversely, it is a very bad practice to leave floating ground points in your circuit. If you are using multiple benchtop instruments simultaneously such as a DC power supply, signal generator, oscilloscope, and digital multimeter, you should create a common ground between all instruments (and your circuit too) to ensure that you get accurate measurements and don’t have strange circuit behavior.

==Demonstration==
Set up a breadboard with a 10k potentiometer as a voltage divider using the wiper as the output pin. Connect an LED and a 560 resistor in series to the potentiometer's output pin.
