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.

What are positive and negative terminals?
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.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
Because it has a potential difference between the positive and negative terminals what can act as an electron pump?
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.
What direction does direct current flow in?
Curren flow from high potential to low potential or simply, positive pole to negetive pole.
Why do electric cell have two terminals?
They are the negative and positive terminals. Higher potential andl ower potential terminals
What direction do the electrical charges flow?
Electrical charges flow from areas of higher potential (voltage) to areas of lower potential. This means that they flow from the positive terminal of a battery to the negative terminal in a closed circuit.
Do electron tend to move a region of high potential or lower potential?
Electrons tend to move from a region of higher potential to a region of lower potential, following the path of least resistance. This movement of electrons contributes to the flow of electric current in a circuit.
The terminals of a diode are called the?
anode positive potential cathode negative potential
WHAT PUSHES THE ELECTRONS TO FLOW?
Electrons flow in a circuit due to the electric potential difference, or voltage, between two points. This voltage creates an electric field that exerts a force on the electrons, causing them to move from a higher potential (positive terminal) to a lower potential (negative terminal).
How do electrons flow in an electric circuit in terms of potential energy?
Electrons flow in an electric circuit from an area of higher potential energy (positive terminal of the battery) to an area of lower potential energy (negative terminal of the battery). This flow of electrons is what creates an electric current in the circuit.
What enables the charges in an electrical ciruit to flow?
The charges in an electrical circuit flow due to the presence of a potential difference, created by a voltage source like a battery or generator. This potential difference provides the force necessary for the charges to move through the circuit, from the higher potential (positive terminal) to the lower potential (negative terminal).
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
What happens to charge as it move through a electric circuit?
Charge moves through an electric circuit by flowing from areas of higher potential (such as the positive terminal of a battery) to areas of lower potential (such as the negative terminal). As the charge flows, it can do work, such as powering a lightbulb or motor, before returning to complete the circuit.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
The electrical potential energy of an electron leaving the negative terminal of a 1.5V battery would be 1.5 electronvolts (eV). This energy is gained by the electron as it moves through the circuit towards the positive terminal.
Why the dc average voltage is having negative value?
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.
What is the driving force for the flow of electrons in battries?
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.
