Chemical energy is stored in a battery, which is converted into electrical energy when the battery is connected to a circuit.
Direct current (DC) is produced by an electric battery. This type of current flows consistently in one direction from the positive terminal to the negative terminal of the battery.
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
Radio waves have the longest wavelengths among all types of electromagnetic energy. They have wavelengths ranging from a few millimeters to kilometers.
A battery is a form of potential chemical energy that can be converted into electrical energy to power devices.
Duracell and Energizer. wat type of battery is thiscar battery 068113144107
For a set rate of power drain and the same battery chemistry, the biggest battery will last the longest. In this case, the 'C' size.
The current leader in energy density and life is lithium chemistry batteries. If you can't get that, go for Alkaline.
Oreck Vacuums are rated the longest as the lasting battery in a vacuum.
currently I'm using macbook white 2010 the battery lasts upto 6hrs...
Dell's lithium Ion batteries are some of the longest lasting on the market.
probably fresh water or salt
you put in one type, leave it on over say 4 hours, VIDEO TAPE the whole thing, check when it went out, then do the same for the next type.
Energizer lasts the longest. It's beats Duracell by about 2 or 3 hours. I just did a science fair project on this, but I used D sized batteries. Still, Energizer is the best to use.
AA energizer
Panasonic lasts the longest.. it worked really long. it lasted 5 hours and the energizer battery only lasted 3 hours.. we did an experiment checking which battery lasted the longest by taking pictures on a camera until the battery died.
Sony's L Series Infolithium battery lasts much longer then the competition.
