FAQs on Fun Video: Introduction to Batteries Video Lecture - General Awareness & Knowledge - Bank Exams

1. What is a battery and how does it work?
Ans. A battery is a device that stores chemical energy and converts it into electrical energy. It consists of two electrodes, an anode (negative electrode) and a cathode (positive electrode), separated by an electrolyte. When a circuit is connected to the battery, a chemical reaction occurs at the electrodes, producing a flow of electrons from the anode to the cathode, creating an electric current.
2. How long do batteries last?
Ans. The lifespan of a battery depends on various factors, including its type, usage, and environmental conditions. Generally, disposable alkaline batteries can last between one to two years, while rechargeable batteries can last several years with proper care. However, heavy usage or extreme temperatures can significantly reduce their lifespan.
3. Can batteries be recycled?
Ans. Yes, batteries can be recycled to recover valuable materials and minimize environmental impact. Many battery retailers and recycling centers accept used batteries for recycling. It is important to recycle batteries properly as they contain hazardous materials that can harm the environment if not disposed of correctly.
4. Are all batteries the same?
Ans. No, batteries come in various types and sizes, each designed for specific applications. Common battery types include alkaline, lithium-ion, nickel-metal hydride (NiMH), and lead-acid. They differ in their energy capacity, voltage, self-discharge rate, and rechargeability. It is important to choose the right battery type for the intended device or application.
5. How should batteries be stored when not in use?
Ans. When not in use, batteries should be stored in a cool, dry place at room temperature. Extreme temperatures can degrade battery performance and shorten their lifespan. It is also recommended to store batteries in their original packaging or in separate compartments to prevent contact with metal objects or each other, which can cause short circuits.
