Outside the battery:
- The path for conventional current goes from the positive terminal (+, usually a red wire) to the negative terminal (−, usually a black wire).
- A wire's electrons flow from the negative (−) terminal to the positive (+) terminal.
Since the current forms a continuous a loop in the same direction, the direction inside the battery is "backwards".
Inside the battery:
- Conventional current flows from the negative (−) terminal to the positive (+) terminal.
- Positive ions flow from the negative (−) terminal to the positive (+) terminal.
- Negative ions flow from the positive(+) terminal to the negative (−) terminal
Conventional current assumes that all flowing charges are positive. It simplifies the situation because it hides the more complicated electrons, positive ions, and negative ions.

Why is electricity sometimes described as a flow of electrons?
Flowing electrons makes electricity (they flow from negative to positive. ). You need a circuit or a path for the electrons to move through, a power source like a battery or a generator, and something to use the electricity, like a light bulb...
Is electricity is amount of electrons?
Electricity is the flow of electrons
Are the chemical reactions of a battery an exothermic or an endothermic reaction?
EXOTHERMIC because the electrons flow from one to another so its exothermic NOT endothermic! B/c it RELEASES energy!
Do batteries give off electrons to circuits?
When any conducting material is connected to provide a continuous path between the two terminals of a battery, electric current flows through it. On the microscopic level, electric current is really the flow of electrons, from the battery's negative terminal, through the conducting path, to its positive terminal.
What negatively charged particles are responsible for the flow of electricity?
Electrons are the negatively charged particles to which the flow of electricity is attributed.
What current has a negative sign and what does it indicate?
Electrical current in copper is the flow of electrons which are negaitve charge particles. In a typical battery, electrons flow from the negative (bottom) side to the positive (top, nipple) side. However, the engineering convention is to call the "plus" side of the battery the source so current is said to flow from the plus side to the negative side -- which is the opposite to the physical flow of electrons.
What end does electrons flow in a circuit?
the positive side, the negative side is usually just a ground
What does the positive side of the battery do?
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
Why do you have to connect one wire to each end of the battery for the circuit to work?
The battery pushes electrons out one side, and attracts them back to the other side. Without a closed circuit, the electrons can flow for a brief time, but they would quickly accumulate on some connected object. Since electrons repel one another, they will quickly come to the point where no further electrons can get into an object.
What flows through wires that are hooked to a battery?
Electrons flow through wires that are hooked to a battery. The battery's negative terminal repels the electrons, while the positive terminal attracts them.
Does electricity flow more than 1 pathway?
An electric current is usually thought of as a flow of electrons. When two ends of a battery are connected to each other by means of a metal wire, electrons flow out of one end (electrode or pole) of the battery, through the wire, and into the opposite end of the battery.
What is the driving force for the flow of electrons in battery's?
potential difference between electrodes
How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
How do electrons flow in an electric in terms of potential difference?
Electrons naturally tend to flow from a point that has a more negative potential, to one that is more positive. Inside the battery, of course, it is the other way round; they flow from positive to negative - the battery provides the required energy. In this case, the battery can be considered an electron pump.
What is a parralel circuit?
a parallel circuit is an electrical circuit with at least two ways for electrons to flow, joining up again to join the -/+ side of the battery, completing the circuit
How do circuits work?
Circuits need 3 things to work. They need a load, (what the power goes on) power source, (the battery) and connectors (the wire inbetween). Circuits use electrons to flow from the negative side of the battery and around the circuit back to the battery. This repeats until the circuit breaks.
What power source contains a chemical that releases electrons on one side and a chemical that accepts the electrons on the other side.?
A Battery
