Volts. Volts is another term for potential.
A battery has a potential difference between its terminals due to a build-up of charge separation (positive and negative terminals). This potential difference can act as an electron pump by causing the flow of electrons from the negative terminal to the positive terminal through an external circuit, thereby generating electrical energy.
Just arbitrary choice by Benjamin Franklin when he defined "conventional" electric polarities.The negative terminal has higher number of electrons, but Franklin knew nothing of electrons as they were not discovered until more than a century later.Mathematically it makes no difference whether the positive terminal or negative terminal has higher potential, as long as one is consistent one way or the other in the equations.
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Positive and negative terminals are locations on a device or component where electrical connections can be made. The positive terminal typically has a higher voltage potential, while the negative terminal has a lower voltage potential. Ensuring proper connection to these terminals is important for the correct operation of electrical circuits.
Energy flows from the negative terminal to the positive terminal of a battery.
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
The driving force for the flow of electrons in batteries is the potential difference, or voltage, created between the positive and negative terminals. This potential difference causes the electrons to move from the negative terminal (anode) to the positive terminal (cathode), creating an electric current.
The positive + terminal is slightly larger.

This potential difference can act as an electron pump by causing the flow of electrons from the negative terminal to the positive terminal through an external circuit, thereby generating electrical energy.
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.

The driving force for the flow of elections in batteries is the difference in electrical potential between the positive and negative terminals. This potential difference, known as voltage, creates an electric field that causes electrons to flow from the negative terminal to the positive terminal, generating an electric current.
Yes, a voltmeter has a positive terminal, typically marked with a "+" sign, and a negative terminal, marked with a "−" sign. When measuring voltage, the positive terminal should be connected to the higher potential point in the circuit, while the negative terminal connects to the lower potential. This arrangement allows the voltmeter to accurately display the voltage difference between the two points.
A battery has two terminals—positive and negative—because they facilitate the flow of electric current. The positive terminal, often marked with a "+" sign, attracts electrons, while the negative terminal, marked with a "-", releases them. This difference in charge creates an electric potential difference, allowing electrons to flow from the negative terminal to the positive terminal when the circuit is closed, thus providing electrical energy for devices.
anode positive potential cathode negative potential
In an electric cell, there are excess electrons at the negative terminal. This accumulation of electrons creates a negative charge, which leads to a potential difference between the negative and positive terminals. When a circuit is completed, the electrons flow from the negative terminal to the positive terminal, providing electric current. This movement of electrons is what powers electrical devices connected to the cell.
