Q1. A 25-year-old scientist uses a Rogowski coil to measure the current in a power transmission line. What is the main advantage of this coil?
Answer: Non-invasive measurement
Explanation: Rogowski coils are non-invasive, allowing for current measurement without disrupting the flow. High sensitivity is a feature of some measurement tools, low cost is not unique to Rogowski coils, and high accuracy is a general goal of measurement instruments.
