A volt is not a unit of energy. It is a unit of something that in English is usually called "voltage". It is really about electric potential. One volt is equal to one joule/coulomb; that means that if an electric charge of 1 coulomb goes through a potential difference of 1 volt, it will either gain or lose 1 joule of energy.
none the energy is in the amps
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
An electron volt (eV) is a unit of energy equal to the energy gained by an electron as it moves through a potential difference of one volt. It is commonly used in atomic and subatomic physics to describe the energy of particles at the atomic and molecular scale.
That can vary a lot, depending on the size of the battery. The "volt" is not an indication of energy stored. It simply means that (on average), each electron is pushed at a certain energy. To get the total energy, you would also need to know how much current it can provide, and for how long. The total energy can be calculated as the product of the voltage, the current, and how long this current flows (assuming a constant current; otherwise you would have to integrate).
electron volt
On would use a 12 volt battery for a lot of things. For example, a lot of Fisher Price toys and games, power wheels vehicles have a type of 12 volt system.
ask your v*gina ..
with volt meters
An electron-volt (eV) is a unit of energy used in physics. It is the amount of energy gained by an electron when it moves through an electric potential difference of one volt. Scientists use electron-volts as an alternate unit for measuring energy in subatomic particle interactions and in the field of particle physics.
energy per watt
It depends on the use it is being put to. It is sufficient for a 24 volt circuit. Too much for a 12 volt circuit and too little for a 240 volt circuit.
Power or energy cannot be measured in volts. The only thing you can say is one - the 9 volt battery - has a higher voltage than the other, the 6 volt battery. If you are asking about the power or energy contained in a battery, then the amount iof energy it can supply depends mostly on its physical size that is determined by the battery "type".
