1 volt = 1 joule per coulomb
12 joule/coulomb x 2.5 coulomb = 30 joules
That's the energy removed from the battery and dissipated
by the circuit, either as heat or radiation.
A battery supplies energy to move electricity through a circuit (Remember, a circuit is a wire.)
A battery
In a circuit, the energy needed to move electricity is provided by a power source such as a battery or a generator. This power source creates a voltage difference between the circuit's components, which pushes the electric charges to flow through the circuit.
The object is called a power source, such as a battery or a generator, which provides the energy needed to move current through a circuit.
The answer is Charges
A voltage source, such as a battery or generator, provides the energy needed to move electricity through a circuit by creating a potential difference (voltage) that drives the flow of charges. This voltage difference pushes the electrons through the circuit, allowing them to power devices or perform work.
A device that moves electrons along a path is called a circuit. In a circuit, electrons flow from the negative terminal of a battery, through the components in the circuit, and back to the positive terminal of the battery, creating electrical energy.
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.
Charges in a circuit move in response to an electric field created by a power source like a battery. This electric field exerts a force on the charges, causing them to move through the circuit. This movement of charges is what allows electrical energy to be transferred from the source to the electrical components in the circuit.
A battery creates an electric field within the circuit, which applies a force on the electrons, causing them to move. This movement of electrons creates an electric current that flows through the circuit, allowing electrical devices to function.
In a simple circuit, energy is transferred from the power source (e.g., battery) to the components (e.g., light bulb) through the flow of electrons. The power source provides the electrical potential (voltage) that pushes the electrons through the circuit. As the electrons move through the components, they transfer their energy, causing the components to do work (e.g., produce light or heat).
No, is it incorrect to say that a battery produces the charges that circulate in a circuit. Some might suggest that a battery is a current source, but the battery should most properly be considered a voltage source. It generates the electromotive force (emf or voltage) that causes charges to move. (It does this through electrochemical reactions.) The charges that circulate in a circuit (which might be termed the current flow) are already in the conductor and components. All the battery does is produce the voltage (the force) to move charges. Let's look at current flow and see why things might be best looked at in the manner we've stated.Note that the way a battery moves charges is to "inject" an electron into the circuit where it is tied to the negative terminal of that battery. The electron causes one electron in the circuit at the terminal to "move over" and that will cause another electron to "move over" and so on. This will continue until the "last electron" in the circuit at the positive terminal of the battery leaves the circuit and "goes into" the battery. Current flow in the circuit is like musical chairs with electrons everywhere in the circuit "moving over a space" to cause the current flow.Having gone through all that, it should be easier to see why a battery probably should not be considered the producer of charges that circulate in a circuit. Rather, the battery is the source of the voltage that drives the charges (the current) in the circuit.
