Supplied test record: In a checked low-voltage circuit, sample C completes the path and the lamp lights. A known conducting connection works before and after. Thermal conductivity concerns energy transfer through a temperature difference; electrical conductivity concerns charge movement. These are different tests. Use records only here: no hot water, mains, hot pans or child-led heating; adults control approved low-voltage equipment.
