Exam-style question
Try this first
In a potential divider circuit with a total resistance of 12 Ω and a supply voltage of 24 V, what is the output voltage across a 6 Ω resistor? Scenario focus: a household appliance problem, where energy transfer over time is the central idea.
- A.8 V
- B.12 V
- C.6 V
- D.18 V
Model answer
What a good answer should say
- 12 V
Explanation
Why this works
The correct answer is 12 V. In this version, the deciding idea is a household appliance problem, where energy transfer over time is the central idea.
That makes the correct option the one that uses the appropriate electricity quantity and unit, while the distractors either swap related circuit quantities or apply a rule from the wrong circuit situation.
