Supplied test record: Sample L lights a checked low-voltage lamp, but the class has no thermal measurements for L. 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.
