Question
- A. Use explain why a high potential difference in transmission cables reduces current for a given power transfer in the specific circuit or quantity named in the question.
- B. Assume high 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 explain why a high potential difference in transmission cables reduces current for a given power transfer in the specific circuit or quantity named in the question.
Explanation
