What is the source of electrons that flow through a wire with a battery and light bulb connected in a simple circuit?
The electrons come from the metal of the wire, light bulb filament, and plates inside the battery. In other words, they are already everywhere in the circuit, even before it is connected together.
The electrons are made to move (and thus do work, e.g. heating the filament to make light) by the electromotive force generated by the corrosion of the metal plates inside the battery by the electrolyte between those plates.
Note: while the electric current flows around the circuit at a speed close to the speed of light, individual electrons within that current actually move very slowly due to the fact they keep bouncing off atoms and other electrons thus performing a "random walk". These speeds are on the order of millimeters per hour.

How does a battery work in a circuit to provide electrical power?
A battery works in a circuit by converting chemical energy into electrical energy. When connected in a circuit, the battery's chemical reactions create a flow of electrons, which generates a voltage difference. This voltage difference drives the flow of electrons through the circuit, providing electrical power to the connected devices.
How is the energy stored in the battery put into action?
When a battery is connected to a circuit, a chemical reaction inside the battery generates electrons that flow through the circuit, creating an electric current that powers the connected device. This flow of electrons provides the energy needed for the device to function.
How does a battery store and release potential energy?
A battery stores potential energy through a chemical reaction that creates a buildup of electrical charge. When connected to a circuit, the stored energy is released as electrons flow from the battery through the circuit, powering devices.
What particles run through circuits attached to a battery?
Electrons are the particles that run through circuits attached to a battery. When a circuit is connected to a battery, the voltage difference provided by the battery allows electrons to flow from the negative terminal to the positive terminal, creating an electric current.
How does electrical energy travel through a circuit?
Electrical energy travels through a circuit by flowing through a closed loop of conductive materials, such as wires. The energy is generated by a power source, such as a battery or generator, and is carried through the circuit by the movement of electrons. The flow of electrons creates a current that powers the devices connected to the circuit.
What is the positive end of a battery and how does it affect the flow of electricity within a circuit?
The positive end of a battery is called the anode. It provides a source of electrons that flow through the circuit to the negative end, called the cathode. This flow of electrons creates an electric current that powers the devices connected to the circuit.
How does electricity flow from a battery through a circuit?
Electricity flows from a battery through a circuit when a complete path is created for the electrons to move. Electrons move from the negative terminal of the battery through the circuit to the positive terminal. This flow of electrons creates an electric current that powers the components in the circuit.
How do chemical energy is transferred in to electrical energy?
Chemical energy can be converted into electrical energy through a chemical reaction in a battery. When the battery is connected to a circuit, the reaction releases electrons, which flow through the circuit as an electric current, producing electrical energy.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The electric current in a circuit is caused by the flow of electrically charged particles, typically electrons, through the wires. When the battery is connected, it creates a potential difference (voltage) that pushes the electrons to move from the negative terminal to the positive terminal, creating a continuous flow of current in the circuit.
What is the potential energy of a charged battery?
The potential energy of a charged battery is the stored energy that can be converted into electrical energy when the battery is connected to a circuit. This energy is a result of the separation of positive and negative charges within the battery, creating a potential difference that can drive the flow of electrons through a circuit.
How is the energy of a battery transformed?
The chemical energy stored in a battery is converted into electrical energy when the battery is connected to a circuit. This electrical energy powers devices by creating a flow of electrons through the circuit, which can then be used to perform work such as lighting up a bulb or running a motor.
How does electricity flow through a battery?
In a battery, electricity flows when chemical reactions within the battery create an imbalance of electrons between the positive and negative terminals. This creates a potential difference, or voltage, which forces electrons to flow from the negative terminal to the positive terminal through an external circuit, powering devices connected to the battery.
