When an electric current coil of a wattmeter is connected to the electric current path R and the voltage coil is connected between the electric current R path and the neutral side of the balanced three phase supply, it shows 10 kW. The line voltage along the phase sequence RYB is 400 V. The current drawn by the current path is 54 A. What is the new reading of the wattmeter if the voltage coil is connected between the lines B and the Y paths, even if the electric current coil is continuously present in the line R?

A teacher is trying to teach the concept of good & bad conductors of electricity to class VI students. He begins by providing the definition of two terms. He then demonstrates how placing a good conductor like a safety pin between two ends of an open circuit consisting of a battery and a bulb completes it and bulb begins to glow. On the other hand, placing a poor conductor like a plastic scale does not complete the circuit and the bulb does not glow. He then invites the students turn-wise to his desk & asks them to themselves verify this. How would you evaluate the approach from an inquiry - oriented perspective?
