Exam-style question
Try this first
A circuit has a total voltage of 24 V and a total resistance of 6 Ω. What is the current flowing through the circuit? Scenario focus: a series-circuit fault-finding problem, where the answer must show why resistances add directly.
- A.4 A
- B.6 A
- C.2 A
- D.8 A
Model answer
What a good answer should say
- 4 A
Explanation
Why this works
The correct answer is 4 A. In this version, the deciding idea is a series-circuit fault-finding problem, where the answer must show why resistances add directly.
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.
