An ordinary dry cell is pretty well answered by:
Anode: Zn → Zn2+ + 2e-
Cathode: 2NH4+ + 2MnO2 + 2e- → Mn2O3 + H2O + 2NH3
when the wire is disconnected from the dry cell you feel not hot
A dry cell battery does not use current it produces a current when connected to an electrical load. The type of current that the dry cell produces is DC (direct current).
A wet cell A cell that contains a solid electrolyte is a dry cell.
A dry cell works when kept in sunlight because it is comprised of a metal called electrode or graphite rod. The sunlight helps the cell to maintained 1.5 volts and stored a charge of one coulomb.
How does the voltage measured across a dry cell ompare with the voltage drop measured across three bulbs in series?

primary cell (chemical cell)
the chemical inside the dry cell is the fluid where chemical reaction take place this fluid is CYTOPLASM
A wet cell and a dry cell are the same in that they each have an anode, a cathode and and electrolyte. All three components are different chemically. The anode and the cathode will exhibit a voltage difference when placed in the electically conductive electrolyte. The voltage and reaction between the three parts of the cell are chemical reactions. A wet cell is different from a dry cell in that the electrolyte in the wet cell is a liquid where the so-called dry cell has an electrolyte that is either damp, moist or in a gelatinous form. ( The electrolyte is not actually "dry".) Otherwise the cells are the same. The cell may be a primary cell that is depleted as one of the elements is chemically consumed or the cell may be rechargable by reversing the chemical reaction.
A lead acid battery uses liquid acid to cause a reaction that will lead to production of a direct current. However, a dry cell does not have any liquid but it instead uses solid chemicals that can react to produce a direct current.
Oxidation occurs at the anode ("an ox") and reduction occurs at the cathode ("red cat").See the Web Link to the left for the specific reaction in a dry cell.
Yes common dry cell is a primary cell. No reversible reaction and hence no chance of charging. So use and throw type. But secondary cells could be put for charging and we can use it again and again after charging.
no lechlanche cell is not a dry cell.
The space between the electrodes in dry cell is filled by a moist paste of ammonium chloride (NH4Cl) and zinc chloride (ZnCl2). ZnCl2 acts as an electrolyte. ZnCl2 provides zinc and chloride ions to complete the complex reaction occurring in the cell.
* A "dry-cell" battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below. * In the most common type of dry cell battery, the cathode is composed of a form of elemental carbon called graphite, which serves as a solid support for the reduction half-reaction. * At the center of each dry cell battery is a rod called a cathode, which is generally made of metal or graphite and is surrounded by an electrolyte paste. The cathode and electrolyte paste are wrapped in paper or cardboard.
Well for one, it would be a dry cell without it... But to explain the other side, it is the chemical reaction that causes the electricity to flow. There is quite a bit out there on what happens at an actomic, level, and how the electron flows as part of the chemical reaction.
There is dry cell and wet cell. A dry cell has not fluid around it. A wet cell is surrounded by fluid of some sort, usually acid.
