∙ 14y ago
Typically 6 cells at approximately 2 volts per cell. The cell voltage varies by the chemicals used to make the cell (lithium would be around 3v for instance)
To charge a typical 12V battery it's common to use 13.4V to 13.8V

A battery consists of five dry cells connected in series if the voltage developed by the battery is?
Approximately 7.5 volts, under no-load conditions, assuming that each cell is exactly at 1.5 volts each (which I assure you, it doesn't really happen that way in the real world, but it's close enough).When cells are connected in series, the voltage is the sum of all individual voltages. In this case, with 5 cells in series (each at 1.5V), the total voltage would be 1.5V*5 = 7.5V
What are galvanic batteries?
A galvanic battery is probably most simply described as a battery which consists of a number of voltaic cells in series or parallel. A battery is a group of something, like a battery of guns protecting a harbor, or a battery of tests composing the SAT, or a group of power cells grouped together to equal either more voltage or greater current capabilities. Just for interest sake, individual cellsstarted life being called a Voltaic pile named for the Italian scientist Volta. There was a dish of acid, a bar of zinc, and a bar of a dissimilar metal, say copper, for instance each dipping into the acid. You could measure electrical current between the zinc and copper bars. An old trade name for the zinc plating process was Galvanum. Hence 'Galvanic'. So the any power cell that used an acid and two dissimilar metals used 'Galvanic action' to create electricity from chemical energy, even though zinc may not have been used at all. A Galvanic battery is a group of galvanic power cells packaged within one enclosure. A 9-volt battery is a good example, as it is made of 6 power cells at 1.5 volts each, packaged in the neat little rectangular container that we see all over the place.
List 3 similarities between the two types of cells?
Prokaryotic and eukaryotic cells have in common the genetic material, that is, presence of DNAAlong with DNA, prokaryotic and eukaryotic cells have in common the presence of RNAProkaryotic and eukaryotic cells, both have a cell membrane covering themThe prokaryotic and eukaryotic cells similarities are seen in their basic chemical structures. Both are made up of carbohydrates, proteins, nucleic acid, minerals, fats and vitaminsProkaryotic and eukaryotic cells have in common ribosomes, that are the structures that make up proteinsProkaryotic and eukaryotic cells regulate the flow of nutrients and waste matter that enters and leaves the cellsProkaryotic cells and eukaryotic cells both carry out the basic life process, that is, photosynthesis and reproduction.Prokaryotic and eukaryotic cells need energy supply to surviveProkaryotic cells and eukaryotic cells both have 'chemical noses' that keeps them updated and aware of all the reactions that occur within them and in the surrounding environmentProkaryotic and eukaryotic cells have in common a fluid-like matrix called the cytoplasm that fills the cells.Prokaryotic cells and eukaryotic cells both have a cytoskeleton within the cell to support themProkaryotic cells and eukaryotic cells, both have a thin extension of the plasma membrane. It is supported by the cytoskeleton. It is observed in the flagella and cilia in eukaryotic cells and flagella, endoflagella, fimbriae and pili in prokaryotic cells. This is used for motility, adhering to surfaces or moving matter outside the cells.Some prokaryotic and eukaryotic cells have in common glycocalyces. This is a sugar based structure that is sticky and helps the cells in anchoring to each other, thus, giving them some protection.Prokaryotic cells and eukaryotic cells, both have lipid bilayer known as the plasma layer that forms the boundary between the inside and outside of the cell.
A battery is of five cells joined in series when the externalresistance is 4 ohms the current is1.5amps and when it is 9 ohms the current falls to 0.75 amps calculate the each cell and its internal r?
1. Draw the circuit: A single voltage source in series with Resistance Rs (source resistance) and Rl (load resistance) 2. Using Ohm's law, you know V / R = I, so: V / (Rs + 4) = 1.5 and V / (Rs + 9) = .75 Solve for Rs: Rs = 1.0 ohms. Then solve for V: V = 1.5(Rs) + 6 = 7.5 volts 3. Determine the voltage of each cell (assuming they are equivelant voltages): 7.5/5 = 1.5 volts
What is a car battery made of?
It is made of a plastic case, in which there are 6 compartments, inside each there are several plates made of a frame covered with a lead-based paste. These sit in an acid bath, which works with the plates to make a chemical reaction which makes the battery volts.
How many cells does a 9 volt battery contain?
6 @ 1.5v each The 9 volt battery is a true battery, containing six cells of 1.5 volts each. Most storage devices that we call batteries(i.e. D-cell, AA-cell, AAA-cell) are not batteries, but cells.
Each cell in a typical car battery has a little over what volts?
Each cell in a typical car battery has a little over 1.5 volts. Eight cells per battery equals the battery's total voltage.
Are the car battery cells connected in a parallel or in a series?
Sereies, with each cell about 2.2volts
What is the power output from the battery?
The power output on a car battery will depend on how many cells the battery has. Each cell puts out 2.1 volts.
How many volts does each cell produce if a 12v battery has 6 cells?
2 volts
How does volt effect battery size?
In a roundabout way. Battery in electrics actually means a collection (=two or more) of cells. Assuming it's new or fully charged, each cell will give a voltage acccording to which chemistry it uses(Ni-Cd, NiMh, Li-Po, etc) and a capacity according to its size. So the battery size you get is a combination of how many cells you need to reach the voltage that you want, and the capacity that you want. You could get a whopping voltage out of a battery about the size of a pen if you put together a stack of pea-sized hearing aid batteries, but the capacity wouldn't be much to brag about. In the opposite fashion you could have one cell the size of a soda can that'd have a huge capacity, but not much voltage. Old lead-acid batteries as in submarines could have cells basically the size of a suitcase. Huge capacity, but only two volts each.
How many cells are in a battery?
AnswerAccording to WikiPedia (http:/en.wikipedia.org/wiki/Rechargeable_battery), the nominal cell voltage of a Lead Acid wet-cell battery is 2.1 volts, this implies there are 6 cells in a 12 volt Lead Acid wet-cell battery.
Are car battery cells connected in series or in parallel?
Battery cells are conneted in series. Each cell of a 12v battery averages 2.1v when charged. SERIES 2-4-6-8 and so on
How do you determine the number of cells in a battery?
It depends on the chemistry of the battery. A common alkaline or zinc chloride non-rechargeable battery will be about 1.5v per cell. a NiMh or NiCd rechargeable battery is usually quoted at 1.2v per cell, Lithium Ion cells are generally quoted at 3.7 volts and lead acid at 2v per cell. Divide the pack voltage by the individual voltage of each cell and you will find out how many cells are in the pack.
Of the six separate batteries in a typical car battery each one is called an?
Cell. Each cell is wired in series with the next one. Lead-acid cells produce 2 volts each, thus for 6 cells we get 12 volts.
Why is car battery called a battery?
Its called a battery because it is a group of cells. In the case of a conventional lead-acid battery each cell produces about 2 volts. To obtain 12 volts, 6 of these cells must be combined, forming a battery. Sometimes the term battery is a misnomer. In the case of 1.5v alkaline "batteries" they are technically just one cell.
How many watch batteries and what kind would have to be connected in series to be equivalent to a 9v battery and would it be feasible to do so?
It is the nature of most batteries to put out 1.5 volts per cell. A 9 volt battery will have 6 cells and the size of each cell will relate to it's capacity for energy storage. To make a 9 volt battery from six 1.5 cells, you would hook one wire to all the - post and one wire to all the + post. The end of each wire would now be the + and - wires or post for a battery with 6 cells and 9 volts. If you want to use batterys that have other voltages, just add the volts of each to get the totaled volts. You will need to use like cells.
