Which of these is NOT one of the three key factors that Ohm's law helps establish about resistance in Activity 11.2 (different components give different currents)?

Question
Which of these is NOT one of the three key factors that Ohm's law helps establish about resistance in Activity 11.2 (different components give different currents)?
Different components offer different resistance
Current differs for different components at the same voltage
Some components resist current flow more than others
All components have exactly equal resistance
Answer
All components have exactly equal resistance
Detailed Explanation
The activity shows ammeter readings differ for different components, proving they do NOT have equal resistance.
