Premium Equilateral Glass Prism, 50mm, 60° Safety Supplies_Lab Coats and Aprons Stand-mounted Ingen-Hausz apparatus comparing thermal

Stand-mounted Ingen-Hausz apparatus comparing thermal conductivity of different metal rods through wax coatings that melt at different rates along each rod from the heated end

dropping the bulk of the measured potential across the external resistor so the coil sees only its proportional share of the signal

Built for the classic thermal-expansion demonstration
