FAQs on Dry cell & Mercury cell Video Lecture - JEE

1. What is a dry cell and how does it work?

Ans. A dry cell is a type of battery that uses a paste electrolyte instead of a liquid one. It works by having a zinc container acting as the anode and a carbon rod as the cathode. The paste electrolyte, typically a mixture of ammonium chloride and zinc chloride, provides the necessary ions for the chemical reaction to produce electricity.

2. What are the advantages of using dry cells?

Ans. Dry cells have several advantages over other types of batteries. They are portable, compact, and easy to handle. They also have a longer shelf life, making them suitable for devices that are not used frequently. Additionally, dry cells are less prone to leaking and are more environmentally friendly compared to other battery types.

3. What are the applications of dry cells?

Ans. Dry cells are widely used in various electronic devices such as flashlights, remote controls, portable radios, and toys. They are also used in medical devices, emergency backup systems, and automotive applications. Due to their versatility and reliability, dry cells are utilized in numerous everyday items.

4. What are the disadvantages of using dry cells?

Ans. One of the main disadvantages of using dry cells is that they cannot be recharged. Once they are depleted, they need to be replaced with new ones. This not only adds to the cost but also contributes to environmental waste. Additionally, dry cells have a lower energy density compared to other types of batteries, meaning they provide less power for extended periods of use.

5. What is a mercury cell and is it still in use?

Ans. A mercury cell is a type of battery that uses mercury as one of its components. It works through a chemical reaction between zinc and mercury oxide. However, due to environmental concerns and the toxic nature of mercury, its usage has been largely phased out or restricted in many countries. Safer alternatives, such as alkaline and lithium-ion batteries, are now widely used in place of mercury cells.
