Question

Which cell is used in automobiles and inverters?

• A. Mercury cell
• B. Dry cell
• C. Lead storage cell
• D. Fuel cell

Hint:

Lead storage cells are commonly used in automobiles because of their ability to supply high currents needed for starting engines.

Answer 1

The Correct Option is C

The correct answer to the question about which cell is used in automobiles and inverters is the Lead storage cell. Let us understand why this is the suitable choice by considering the options provided:

1. Mercury cell: Mercury cells are primary cells typically used in small electronic devices like watches and hearing aids. They provide a stable voltage but are not suitable for high current applications required in automobiles and inverters.
2. Dry cell: Dry cells are commonly used in household batteries for flashlights and portable radios. While versatile, they do not provide the high capacity necessary for automotive or backup power applications.
3. Lead storage cell: These are commonly known as lead-acid batteries. They are rechargeable and provide a high current, making them ideal for automotive and inverter applications. Their ability to supply large amounts of power makes them the standard choice for starting, lighting, and ignition (SLI) in vehicles.
4. Fuel cell: Fuel cells convert chemical energy directly into electrical energy through electrochemical reactions, typically hydrogen and oxygen. While promising for vehicles, they are not the typical choice for current mainstream automobiles and backup inverters.

Thus, the Lead storage cell is the correct choice because its characteristics perfectly suit the requirements for use in automobiles and inverters.
