The cell used in artificial satellite is:

Options

A. solar cell
B. dry cell
C. Daniell cell
D. voltaic cell

Answer

**Step-by-Step Solution:**

1. **Understanding the Environment of Artificial Satellites:**
- Artificial satellites operate in space, where they are exposed to solar radiation. This means they can harness energy directly from the sun.

2. **Identifying Types of Cells:**
- There are various types of cells that can be used for power generation, including dry cells, Daniel cells, and solar cells.

3. **Evaluating the Suitability of Each Cell:**
- **Dry Cells:** These require recharging and are not efficient for long-term use in space.
- **Daniel Cells:** Similar to dry cells, they also require maintenance and recharging, making them impractical for satellites.
- **Solar Cells:** These cells convert solar energy directly into electrical energy and can continuously recharge themselves using sunlight.

4. **Conclusion:**
- Given the conditions in space and the need for a reliable and self-sustaining power source, the most suitable cell for use in artificial satellites is the solar cell.

**Final Answer:**
The cell used in artificial satellites is the **solar cell**.
