Because it is portable
Only in that it can store energy. However, the energy stored in a capacitor is usually very small, compared to a battery; and it can only hold the energy for a short time.
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".
Brake lights draw their energy from the vehicle's battery.
The battery is supplying electrons by a process of chemical reaction.
Sure. But not much water, a 9 volt battery has very little power (energy).
because it is portable
The are portable.
it can be either renewable or nonrenewable resource.
i dont no?
They contain chemical energy. If you are charging a battery, it has electric energy.
Uranium is not a renewable energy resource however their is enough of it that it counts as an 'Alternative Resource'.
The Earth's major energy resource is the energy coming form the Sun.
battery has chemical energy which is converted into electrical energy by the battery........
Mainly because it isn't an energy resource.
what is the science behind this resource/type of energy
the energy which can be used again and again for our use like solar energy, wind energy to use electricity. the others types of energy resource which will be renewable. it is present more in rajasthan
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.
