*Question T5B08:
Which is equal to 1,000,000 picofarads?*  

*Correct Answer is  B: 1 microfarad*  

### AI Response: (may contain errors)  

To determine which option is equal to 1,000,000 picofarads (pF), we need to convert picofarads to microfarads (µF). 

1. **Understanding the conversion**:
   - The relationship between picofarads and microfarads is given by:
     $$1 \text{ µF} = 1,000,000 \text{ pF}$$
   - Therefore, to convert picofarads to microfarads, we can use:
     $$\text{Value in µF} = \frac{\text{Value in pF}}{1,000,000}$$

2. **Calculating the conversion**:
   - For 1,000,000 pF:
     $$\text{Value in µF} = \frac{1,000,000 \text{ pF}}{1,000,000} = 1 \text{ µF}$$

This shows that 1,000,000 picofarads is equal to 1 microfarad, making option B the correct answer.

### Explanation of Choices:
- **Choice A: 0.001 microfarads**
  - This is incorrect because:
    $$0.001 \text{ µF} = 1,000 \text{ pF}$$
  - This is much less than 1,000,000 pF.

- **Choice B: 1 microfarad**
  - This is correct as shown above. 

- **Choice C: 1000 microfarads**
  - This is incorrect because:
    $$1000 \text{ µF} = 1,000,000,000 \text{ pF}$$
  - This is significantly more than 1,000,000 pF.

- **Choice D: 1,000,000,000 microfarads**
  - This is incorrect because:
    $$1,000,000,000 \text{ µF} = 1,000,000,000,000,000 \text{ pF}$$
  - This is vastly greater than 1,000,000 pF.

### Summary:
- The correct answer is **B: 1 microfarad** because 1,000,000 picofarads converts directly to 1 microfarad.
- The other choices are incorrect due to their respective conversions being either too low or too high compared to 1,000,000 pF.
