The short answer is that they don't.

But that doesn't help you much.

Electrons flow from the negative terminal to the positive terminal.

Why?

Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it.

Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).

What are the functions of the positive and negative electrodes in a battery?

The positive electrode in a battery is where oxidation occurs, releasing electrons. The negative electrode is where reduction occurs, accepting electrons. This flow of electrons creates an electric current that powers the device.


What is the function of the positive electrode and negative electrode in a battery?

The positive electrode in a battery is where the electrons are released during the chemical reaction, while the negative electrode is where the electrons are received. This flow of electrons creates an electric current that powers the device connected to the battery.


What does a battery positive and negative diagram illustrate?

A battery positive and negative diagram illustrates the flow of electric current within a circuit, showing the direction in which electrons move from the negative terminal to the positive terminal.


What are the functions of the positive and negative terminals in a battery diagram, and how do they contribute to the overall operation of the battery?

The positive terminal in a battery diagram is where electrons flow out, while the negative terminal is where electrons flow in. The positive terminal provides a source of electrons, while the negative terminal accepts electrons, creating a flow of electric current. This flow of electrons is what powers the battery and allows it to provide electrical energy to devices connected to it.

In a battery electrons flow from where?

In a battery, electrons flow from the negative terminal (anode) towards the positive terminal (cathode) through the external circuit, creating an electric current.


Why do batteries have positive and negative energies?

Batteries have positive and negative terminals due to the flow of electric charge, which is driven by chemical reactions within the battery. The positive terminal, or cathode, attracts electrons, while the negative terminal, or anode, releases electrons. This difference in charge creates an electric potential that allows for the flow of current when the battery is connected in a circuit. Essentially, the positive and negative energies enable the battery to store and release electrical energy efficiently.


What is current in the battery called?

A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.


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.
