Is there such a thing in electrical circuits, or anywhere else? Or is this just considered reverse polarity, or 0V?

As mentioned above the zero value of the electric potential is typically set to zero in those cases in which the electri potential falls to zero at infinity. However there are instances one runs into when working problems in electrostatics. For example; if you were studying electrostatics then a well-known problem is to find the electric potential of an infinitely long line of charge which has a uniform linear charge distribution. In this case the electric potential does not go to zero at infinity. The zero potential is then chosen to be at an arbitrary distance from the line of charge. Closer to the line the electric potential is zero, further from this distance the electric potential is positive.nuby said:Is there such a thing in electrical circuits, or anywhere else?

Negative electrical potential is a measure of the electric potential energy per unit charge at a certain point in an electric field. It is also known as voltage and is usually measured in volts (V).
The main difference between negative and positive electrical potential is the direction of the electric field. Negative potential indicates that the electric field points towards the location of the negative charge, while positive potential indicates that the electric field points away from the location of the positive charge.
Negative electrical potential is caused by the presence of negative charges, such as electrons, in an electric field. These negative charges are attracted to positive charges and will move towards them, creating a potential difference.
Negative electrical potential can be measured using a voltmeter, which is a device that measures the potential difference between two points in an electric field. The negative potential will be indicated by a negative value on the voltmeter.
Negative electrical potential has various applications in everyday life, such as in batteries, where it is used to power electronic devices. It is also used in electric circuits to control the flow of electricity and in electrostatic precipitators to remove pollutants from the air.
