what is a dry cell? state its disadvantages
Answers
Answer:
Dry cell or Leclanche cell is a primary cell having a zinc anode, a carbon (graphite) cathode surrounded by manganese dioxide, and a paste containing ammonium chloride as electrolyte. The electromotive force (emf) produced by a dry cell is 1.5 V. Dry cell is not reversible and therefore have a limited operating life.
Disadvantages of dry cells:-
Dry cell batteries carry an inherent risk due to the chemicals inside of them. If they are exposed to too much heat (such as being placed too close to or actually in a fire) dry cell batteries can rupture and explode. The contents of the battery are dangerous to people, and the chemicals are highly acidic to the skin.
