How many cells are in a D cell battery?

Answer 1

The`D' sized battery, `AA", `AAA` and `C' sized batteries are manufactured to have a nominal 1.5 volts.

Answer

The electromotive force (open-circuit voltage) produced by a cell is a function of the materials used in the manufacture of its electrodes, and has nothing whatsoever to do with it physical size.

The electrochemical series of metals lists the potentials of various metal electrodes in comparison with a hydrogen electrode, which serves as a zero reference. For example, the simplest cell has a copper electrode and a zinc electrode. From the electochemical series, the potential of copper is found to be +0.34 V, and the potential of zinc is found to be -0.76 V. So, the potential difference between a copper and zinc electrode will be 0.34 - (-0.76) = 1.1 V.

The physical size of a battery (e.g. AAA, AA, etc.), providing they are of the same type, is a measure of the cell's charge capacity (expressed in ampere hours) and not of its emf.

Answer 2

== == The output voltage produced by a single cell, dry cell battery is the same for any size [AAA, AA, C, D, etc.], but the voltage does vary depending on the components of which the battery is made. For example a fresh/new Carbon-Zinc dry cell will produce one and a half [1.5] volts, while a Nickel-Cadmium [Ni-Cad] will produce one and a quarter [1.25] volts, and a Nickel-Metal Hydride [Ni-Mh] will produce one and two tenths [1.20] volts. These voltages are for a new, unused battery. As the battery is used, chemical reactions between the components cause the voltage output to decrease. However, "rechargable" batteries such as the Ni-Cad and the Ni-Mh batteries can be "recharged" for a limited number of "cycles" [a cycle is defined as one full discharge followed by one full recharge]. In these rechargable batteries, the discharging process causes chemical reactions between the components which can be reversed by the recharging process. There are limitations however, and eventually the battery components become used up to the point that recharging becomes less and less effective.
1.5v. The same as many alkaline batteries. Even most watch batteries deliver 1.5 volts. The difference between a D cell and an AA, AAA and C, and many others, aside from the size, is that the D cell will last longer. It can produce more milli amp hours (MaH) of electricity before it dies. Typically, appliances and electronics that use D batteries use a lot of power, and therefore would drain smaller batteries very quickly.

Answer 3

One, The whole D cell battery is the cell.

Answer 4

If you connect the '+' end of one to the '-' end of the other then the voltage between the unconnected ends will be about 3 volts.

Answer 5

About 1.5 volts.
