An electric bulb converts electrical energy into

Options

A. sound energy
B. mechanical energy
C. nuclear energy
D. none of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Function of an Electric Bulb:**
An electric bulb is designed to convert electrical energy into other forms of energy when it is powered on.

2. **Identifying the Forms of Energy Produced:**
The primary forms of energy produced by an electric bulb are:
- **Light Energy:** When the electric current passes through the filament (usually made of tungsten), it heats up and emits light.
- **Heat Energy:** As the filament heats up, it also releases heat energy.

3. **Evaluating Other Energy Forms:**
- **Sound Energy:** An electric bulb does not produce sound energy as its primary function.
- **Mechanical Energy:** An electric bulb does not convert electrical energy into mechanical energy.
- **Nuclear Energy:** An electric bulb does not convert electrical energy into nuclear energy.

4. **Conclusion:**
The electric bulb primarily converts electrical energy into light energy and heat energy. Therefore, the correct answer is that it converts electrical energy into light and heat, and none of the other options (sound, mechanical, or nuclear energy) are correct.

**Final Answer:**
An electric bulb converts electrical energy into light energy and heat energy.
