Which of these will generate electric current when kept in sunlight but will not generate when kept in the dark ?

Options

A. Car battery
B. Button cell
C. Solar cell
D. Dry cell

Explanation

To solve the question "Which of these will generate electric current when kept in sunlight but will not generate when kept in the dark?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Options**:
- The options given are:
- Car Battery
- Button Cell
- Solar Cell
- Dry Cell

2. **Analyze Each Option**:
- **Car Battery**:
- A car battery contains rechargeable cells. It does not generate electric current from sunlight; it stores and supplies electrical energy. Therefore, it does not fit the criteria.

- **Button Cell**:
- Button cells are primary cells used in devices like watches. They cannot be recharged once depleted. They also do not generate electric current from sunlight. Thus, this option is not correct.

- **Solar Cell**:
- Solar cells are specifically designed to convert sunlight into electrical energy. When exposed to sunlight, they generate electric current, but they do not produce current in the dark. This option meets the criteria of the question.

- **Dry Cell**:
- Dry cells are also primary cells that convert stored chemical energy into electrical energy. They do not rely on sunlight to generate electricity. Hence, this option is not correct.

3. **Conclusion**:
- After analyzing all the options, the only device that generates electric current when kept in sunlight and does not generate in the dark is the **Solar Cell**.

### Final Answer:
The correct answer is **Solar Cell**.
