Answers
Explanation:
A dry cell uses a paste electrolyte, with only enough moisture to allow current to flow. Unlike a wet cell, a dry cell can operate in any orientation without spilling, as it contains no free liquid, making it suitable for portable equipment. By comparison, the first wet cells were typically fragile glass containers with lead rods hanging from the open top and needed careful handling to avoid spillage. Lead–acid batteries did not achieve the safety and portability of the dry cell until the development of the gel battery. Wet cells have continued to be used for high-drain applications, such as starting internal combustion engines, because inhibiting the electrolyte flow tends to reduce the current capability.
A common dry cell is the zinc-carbon cell, sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, the same as the alkaline cell (since both use the same zinc–manganese dioxidecombination).
A dry cell is a type of electric battery, commonly used for portable electrical devices. It was developed in 1886 by the German scientist Carl Gassner, after development of wet zinc-carbon batteries by Georges Leclanché in 1866. The modern version was developed by Japanese Yai Sakizo in 1887.
HERE IS YOUR ANSWER MATE ✌1)Carl gassner invented dry cell in 1868. 2) Highly durable, Operated in any position, Don't have leaking problems like wet cell has,not that much sensitive.3) They are marked to present the positive and the negetive side of the cell.4) Electricity is generally produced in power plant by electromechanical machines.5)It reachs our home from power plant stations through transmission lines and distribution lines. HOPE THIS HELPS U DEAR MATE ✌
