Question
- A. Use calculate resistance when potential difference and current are known in the specific circuit or quantity named in the question.
- B. Assume resistance potential difference means the same thing in every electricity context.
- C. Ignore the circuit arrangement and quote the topic title only.
- D. Swap the stated relationship for its opposite when the numbers look unfamiliar.
Answer
The correct answer is: Use calculate resistance when potential difference and current are known in the specific circuit or quantity named in the question.
Explanation
Use calculate resistance when potential difference and current are known in the specific circuit or quantity named in the question. This is correct because the objective is about calculate resistance when potential difference and current are known, not a loose recall of Current, potential difference and resistance.
