A battery is a low-voltage negative voltage source that can be quickly turned off. What is the difference between a positive and a negative power supply? Current flows only in a direct current (DC) circuit, with one pole being negative and the other being positive. Is negative voltage the same as positive voltage?
What is the rationale for DC power adapter connections to be Center
When the input plug is inserted, it completes the circuit for the negative battery terminal. When a power plug is inserted, it breaks the circuit to the positive terminal of the battery. Power jacks do not have a shunt for the center (pin) contact, so a center-positive power supply would not work in this type of circuit." That''s better!-Frank

Do You Know Whether GND Is Positive or Negative?
The negative pole of a power source (such as a battery) is where electrons flow out. It is the point with a lower potential relative to the positive pole, providing a return path for the current in a DC power supply. Not Necessarily Grounded. The negative terminal is usually grounded in many circuits, but not always.
In a DC circuit, is "negative" synonymous with "neutral"?
I prefer the concept of "Power Supply Return", the place where currents from all loads join up to get back into the power source. That is vehicle chassis in metal bodied cars, vehicle skin in airplanes and missiles, circuit common in electronic gizmos. In aircraft it''s obviously not connected to earth, nor in rubber tired vehicles.

Is battery negative and ''ground'' the same thing? | YBW Forum
Re: Is battery negative and ''ground'' the same thing? The general consensus appears to be yes. But, as others have suggested, connecting to ground does not always mean connecting to the negative terminal of a power supply, which strictly speaking is 0V, so don''t blindly follow the rule with everything you install, especially if you are installing radio equipment.

6 FAQs about [What is the negative pole of the battery power supply]
How does a negative battery pole work?
The negative battery pole is connected to the car’s frame, and each element that is connected to the positive pole has its negative terminal connected to the frame. DC power is a unidirectional current, so electricity flows out of the positive pole and returns through the vehicle frame to complete the connection.
What are the positive and negative terminals of a battery?
The positive side of a battery is where the electrical current flows out, while the negative side is where the current flows in. These sides are commonly referred to as the positive and negative terminals respectively. How can I identify the positive and negative terminals of a battery?
How do you know if a battery pole is positive or negative?
The positive terminal is often marked with a plus symbol (+), while the negative terminal is marked with a minus symbol (-). This marking helps differentiate the two poles and ensures proper connection. Another way to identify the battery poles is by examining the physical appearance of the terminals.
What is a positive pole on a battery?
The positive pole is where the battery’s electrical current flows out to power connected devices or circuits. It is commonly marked with a “+” symbol to indicate its positive polarity. Properly identifying the positive side is crucial to ensure correct installation and connection of the battery.
What is the difference between a positive and negative power supply?
The positive terminal of a crown power supply is typically larger than the negative terminal, usually marked with a plus sign (+) or the word «positive.» Conversely, the negative terminal is generally smaller and usually marked with a minus sign (-) or the word «negative.»
What is a positive pole & a negative pole?
Typically the positive pole connects to one or more devices on the circuit, which have their negative terminals connected to the same ground source to complete the circuit. A common application of this grounding technique is found in most automobiles where the vehicle’s 12-volt battery is the DC power source.
