Question

What do you mean by dry cell? Explain the working and principle of dry cell. Explain the construction of rechargeable batteries and power bank.​

Answer 1

Answer:

Dry cell batteries create electrical energy by converting chemical energy into electricity. The exact means of doing so depends on the type of dry cell battery in question, but the materials that are used are generally zinc and carbon or zinc and manganese dioxide.

It is.generally used intorched, transistors, radios, calculators, tape recorders etc. It consists of a hollow zinc cylinder which is filled with a paste of NH4Cl nad a little ZnCl2. This paste is made with the help of water. The zinc cylinder acts as anode while cathode is a graphite rod (Carbon).

In dry cells, a chemical reaction generates electricity. In the dry cell, oxidation reaction occurs at zinc anode to form zinc cations. Zinc atom loses two electrons to form zinc cations.

Answer 2

• By turning chemical energy into electricity, dry cell batteries generate electrical energy.
• The specific method varies depending on the kind of dry cell batteries, although zinc and carbon or zinc and manganese dioxide are commonly utilised.
• It's found in transistors, radios, calculators, tape recorders, and other electronic devices.
• It is made up of a hollow zinc cylinder filled with an NH4Cl paste and a little amount of ZnCl2.
• With the assistance of water, this paste is created. The cathode is a graphite rod, while the anode is a zinc cylinder (Carbon).
• Electricity is generated in dry cells via a chemical process.
• The zinc anode undergoes oxidation in the dry cell, resulting in zinc cations. To make zinc cations, a zinc atom loses two electrons.
