Electricity, as you probably already know, is the flow of electrons through a conductive path like a wire. This path is called a circuit.

Batteries have three parts, an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit.

The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. You can think of this difference as an unstable build-up of the electrons. The electrons wants to rearrange themselves to get rid of this difference. But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons.

In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.

However, these electrochemical processes change the chemicals in anode and cathode to make them stop supplying electrons. So there is a limited amount of power available in a battery.

When you recharge a battery, you change the direction of the flow of electrons using another power source, such as solar panels. The electrochemical processes happen in reverse, and the anode and cathode are restored to their original state and can again provide full power.

A battery gets its energy from a chemical reaction that occurs between the materials inside the battery. This chemical reaction creates an electric current by moving electrons from one terminal of the battery to the other through an external circuit, which can then power electronic devices.

Batteries make electrical current when a chemical reaction takes place which causes electrons to be attracted to one plate and repeled from another. Chemical potential energy is converted to electrical energy. The battery is flat (dead) when the chemical reaction is completely used up. Electrical cells can use any two unlike metals or other conductors with an acid as an electrolyte. Each metal has its own level of attraction for electrons. A fun experiment is to take a nice juicy orange or lemon. Gently stick it with a copper or brass nail. An inch or so away, stick it with a steel nail (making sure the two nails don't touch inside the fruit). Connect a voltmeter to the two nails and you can see that you have built a battery.

through an electrochemical reaction. in these reactions, an electron is passed from one atom to another, but we take advantage of the fact that we can have the atoms exchange electrons through a wire rather than through direct contact and that produces a current

When we complete the circuit by connecting the external resistance, then at the terminals of battery there develops a potential difference. hence current flows

A battery is what type of energy?

A battery is a form of potential chemical energy that can be converted into electrical energy to power devices.


How do you call the energy inside the battery?

battery has chemical energy which is converted into electrical energy by the battery........


What type of energy is a batery that runs a moving toy?

The battery "is" not energy; it's a battery. The battery has chemical energy stored. When moving a toy, the battery releases electrical energy; i.e., some of the chemical energy in the battery is converted to electrical energy.


How potential energy arises from the battery?

Potential energy in a battery arises from the chemical reactions occurring within it. When a battery is charged, chemical energy is stored in the battery in the form of potential energy. This potential energy is then converted back into electrical energy when the battery is connected to a circuit.


What type of energy is inside a battery?

Chemical energy is stored in a battery, which is converted into electrical energy when the battery is connected to a circuit.

What form of energy does electrical energy become in a battery operated car?

When it flows into the battery, it becomes chemical energy. When it flows out of the battery, it becomes kinetic energy.


When you use a battery you transform chemical energy stored the battery to?

When you use a battery, you transform chemical energy stored in the battery into electrical energy. This electrical energy is then used to power electronic devices or systems.


What form of energy is stored in a battery?

Chemical energy is stored in a battery. When the battery is connected in a circuit, the chemical energy is converted into electrical energy which can power devices.


What is the deffintion of the battery?

A battery is a energy source that helps transfer energy to a energy reciver for example if you have a toy that is powerd by a battery and then you turn the toy on it works right? that is because that juice or energy in the battery is being transferred in to the toy ( energy reciver).


Does A battery converts mechanical energy to chemical energy?

No, a battery does not convert mechanical energy to chemical energy. A battery stores energy in the form of chemical energy and then converts it into electrical energy when needed to power a device.
