*Question G5B04:
How many watts of electrical power are consumed by a 12 VDC light bulb that draws 0.2 amperes?*  

*Correct Answer is  A: 2.4 watts*  

### AI Response: (may contain errors)  

To determine the electrical power consumed by the light bulb, we use the formula for electrical power:

$$
P = V \times I
$$

where:
- $P$ is the power in watts,
- $V$ is the voltage in volts,
- $I$ is the current in amperes.

Given:
- $V = 12 \text{ VDC}$
- $I = 0.2 \text{ A}$

Substitute the given values into the formula:

$$
P = 12 \, \text{V} \times 0.2 \, \text{A} = 2.4 \, \text{watts}
$$

**Explanation:**

1. **Correct Answer (A: 2.4 watts):**  
   - The calculation shows that the power consumed is 2.4 watts, which matches choice A.

2. **Incorrect Choices:**
   - **B: 24 watts**  
     - This would be the result if the current were 2 amperes instead of 0.2 amperes.
   - **C: 6 watts**  
     - This would be the result if the voltage were 30 volts instead of 12 volts, with the same current.
   - **D: 60 watts**  
     - This would be the result if the current were 5 amperes instead of 0.2 amperes.

By using the formula $P = V \times I$, we can see that the correct power consumption for the given voltage and current is 2.4 watts.
