Which type of cell be used if a device requires 75A of current for 15 seconds?

Options

A. Simple voltaic cell
B. Daniel cell
C. Leclanche cell
D. Lead-acid cell

Explanation

To determine which type of cell can be used for a device requiring 75A of current for 15 seconds, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Current Requirement**: The device requires a current of 75A. This is a significant amount of current, indicating that we need a cell capable of delivering high current.

2. **Determine the Duration**: The time duration for which this current is required is 15 seconds. This is a short duration, which is crucial in selecting the appropriate type of cell.

3. **Consider the Types of Cells**: There are various types of cells available, including:
- Zinc-carbon batteries (also known as Leclanché cells)
- Alkaline batteries
- Lead-acid batteries
- Lithium-ion batteries

4. **Evaluate Zinc-Carbon Battery**: Zinc-carbon batteries are commonly used for short bursts of current. They are capable of delivering high current for a brief period, making them suitable for applications requiring a quick discharge of energy.

5. **Conclusion**: Given the requirement of 75A for a short duration of 15 seconds, the most suitable choice is the **Zinc-carbon battery**, also known as the **Leclanché cell**. This type of cell is designed for applications that require high current for short periods.

### Final Answer:
The type of cell that can be used for a device requiring 75A of current for 15 seconds is a **Zinc-carbon battery (Leclanché cell)**.
