Exam-style question
Try this first
In a parallel circuit, two resistors R1 = 12 Ω and R2 = 8 Ω are connected. Calculate the total resistance of the circuit. Scenario focus: a parallel network design problem, where adding a branch changes total resistance differently from a series chain.
Model answer
What a good answer should say
- The total resistance in the parallel circuit is 4.8 Ω.
Explanation
Why this works
The correct answer is The total resistance in the parallel circuit is 4.8 Ω.. In this version, the deciding idea is a parallel network design problem, where adding a branch changes total resistance differently from a series chain.
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.
