Understanding Battery Polarities: A Diagram
The positive terminal also helps maintain the voltage stability of the battery, ensuring a consistent power supply. The negative terminal, often marked with a "-" symbol, completes the electrical circuit by allowing the flow of electrons back into the battery. It is connected to the negative electrode of the battery.
Center Negative vs Center Positive – What''s the Difference?
When the center pin of a center negative power source connects to your pedal, it bypasses the battery''s power. That is because the negative polarity of the power supply connects to the negative polarity of the battery, and the two cancel each other out as this video explained. There are some people on Reddit who discuss the same thing.
Difference between negative terminal and copper ground?
If the power supply is a battery, and the devices in the circuit are designed for a positive supply, then the negative terminal serves as the ground. The positive terminal could also be ground, if all the circuits are designed for a negative supply. ... However, the same circuit could be built using a PNP transistor instead, using a negative ...
Purpose of the Power Supply Ground terminal?
In that case you can leave it open, connect to the negative terminal, or connect it to the positive terminal to make a negative-voltage supply. Or, you could use two of these supplies to make a dual (positive and negative) supply. If you leave it open, the negative terminal could be used as an isolated low-voltage ground for your Arduino circuit.
Help me understand the relationship between positive, negative, …
But, there are many circuits that work differently. Some circuits need a negative voltage, so the positive side of a battery would be "ground". Some circuits need positive and negative voltages, in which case there could be two batteries, one with the negative side attached to ground, and the other with the positive side attached to ground.

Is GND Positive or Negative
VCC often relates to the power supply of Bipolar circuits, while VDD/VSS represent the power supply and "ground" of MOS circuits, respectively. In the context of power supply, GND (Ground) is often associated with the negative pole or terminal of the power supply. The power supply typically consists of two terminals: one positive and one negative.

(Conventional) current will flow ...
Why is the ground pin always connected to the "negative" power supply?
But the ground pin is always connected to the "negative" power supply or the negative part of the battery. This would be like connecting the negative end of the same battery to the GND pin. Again, the history and devices. They conveniently call it the "ground rail" when clearly there''s electricity flowing through it.
