6. Why is an LED better than some other forms of lighting?
- It uses less current
- It has a lower potential difference
- It's an ohmic conductor
7. In a series circuit, the potential difference...
- Is shared between components
- Is the same everywhere
- Is shared between branches
8. In a parallel circuit, the potential difference...
- Is shared between components
- Is the same across all components
- Is shared between branches
9. In a series circuit, the current...
- Adds up
- Is the same everywhere
- Is shared between branches
10. What does Ohm's law state?
- For a resistor at constant temperature, there is no relationship between current and potential difference
- For a resistor at constant temperature, current is directly proportional to potential difference
- For a resistor at constant temperature, current is inversely proportional to potential difference
