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.

Just make sure that the power supply you choose provides isolated 9V DC and at least 250mA (small pedals) or 300mA (large pedals) from a 2.1mm center-negative pin. Isolated Power
When a battery is your power source, what is ground?
In essence, the supply current is returned to the supply through the ground connection. So when your power supply is a battery, it makes perfect sense to connect the (-) side of the battery to your system''s ground pin. Notice that this isn''t just a voltage reference though; it is also the supply return.

Center Negative vs Center Positive – What''s the …
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 …
Why do engineers usually short ground and negative ports on a DC power ...
Short answer: it can prevent damage to the power supply equipment.; Long answer: When its not shorted it means that the power supply is "floating" (i.e. NONE of the terminals is connected to ground) --> thus, although a specified voltage is maintained b/w the +ve and –ve terminals BUT the voltage b/w either +ve and ground OR –ve and ground terminals is …
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.
What is Negative Voltage?
It''s not so much that you "need" negative voltage. But sometimes you get negative voltage in a circuit, and it''s good to know what it is. One example where you get negative voltage is in the astable multivibrator …
In a DC circuit, is "negative" synonymous with "neutral"?
3. Is "negative" always the ground point in a DC circuit? No, not necessarily. While "negative" is often connected to ground, it can also be connected to other reference points or circuits. 4. How is the term "negative" used in relation to voltage in a DC circuit? "Negative" is often used to indicate a lower potential point in a circuit.
Positive vs. Negative: Understanding the Power of Battery Polarities
Backup power supplies, such as uninterruptible power supply (UPS) units and emergency power banks, rely on battery polarities to provide power during outages. Correctly aligning the battery terminals in these devices ensures a seamless transition to battery power when needed, ensuring uninterrupted functionality.

An advantage of negative 48V is that four 12V batteries connected in series create 48V DC usable as a backup power source. Central telecom stations are known to have elaborate arrays of 48V battery banks. One important aspect of telecom power installations is that the polarity of the 48V DC source is setup to be negative with respect to ground.
Where is the Ground in a Simple Electronic Circuit
In most circuits these days, "ground/reference" is the most negative terminal of the power supply, so voltages elsewhere are positive relative to "ground". In some cases, the positive terminal of the power supply is "ground", and voltages elsewhere are therefore negative (there''s one logic family that is supposed to run from a -5.2 volt suppply).
