Exam-style question
Try this first
In a potential divider circuit, what happens to the output voltage if the load resistance connected across the output terminals is decreased?.
- A.The output voltage increases
- B.The output voltage decreases
- C.The output voltage remains constant
- D.The output voltage becomes zero
Model answer
What a good answer should say
- The output voltage decreases
Explanation
Why this works
When the load resistance is decreased, it draws more current from the potential divider, which can lead to a drop in the output voltage due to the increased current flow affecting the voltage across the resistors. This illustrates the impact of load on potential divider performance.
