Question

**Understanding Headlight Connections: Series vs. Parallel**

A car has two headlights, and their power is derived from the car’s battery. The filament in one burns out, but the other headlight stays on. Are the headlights connected in series or in parallel?

- a) Parallel
- b) Series

---

**Explanation**

When analyzing the setup for the car's headlights, consider the following details:

1. **Power Source and Connectivity**:
- The headlights are powered by the car's battery.

2. **Filament Burnout**:
- When the filament in one of the headlights burns out, the other headlight remains operational.

**Analysis**:

If one headlight burns out and the other one stays on, the headlights must be connected in a **parallel** circuit. In a parallel circuit, each headlight operates independently. If one bulb fails (filament burns out), the remaining bulb continues to receive power and remains lit.

### Differences in Circuit Configuration

**Parallel Circuit**:
- Each headlight is connected across the same voltage source.
- If one light fails, the circuit to the other light remains complete, allowing it to continue to function.

**Series Circuit**:
- Each headlight is connected one after the other in a single path.
- If one light fails, it breaks the circuit, causing all lights in the series to stop working.

This principle is crucial for automobile safety, ensuring that in the event of a failure of one headlight, the other continues to illuminate the road ahead.

A student reaches to open a door and gets a small electric shock. She knows that the shock is caused by static electricity, but it seems like in the winter she gets shocked more than in the summer. The student asks her science teacher if there are times of the year when there is more static electricity that builds up than other times of the year. The teacher replies that there is, and it depends on the humidity, or moisture in the air. The more humid the air is, the less static will build up and, therefore, the less you get shocked. Explain why static electricity does not build up as much when the air is humid. In your response, be sure to include: an explanation of static electricity is formed. an explanation of why the student felt a shock when reaching for the door handle. an explanation of how moisture in the air allows static electricity to dissipate. Be sure to consider the completeness of your response, supporting details, and accurate use of terms.
