The ETB-190 trainer is a practical laboratory apparatus designed to experimentally verify Stefan’s Law of Radiation, which states that the power radiated by a black body is proportional to the fourth power of its absolute temperature (P ∝ T⁴). In this setup, an incandescent lamp acts as the radiating body, and its filament's resistance is used to estimate temperature changes as current flows.

Key features:

  • Incandescent lamp serving as a thermal radiating body

  • Built-in constant regulated (C.R.) power supply

  • Two digital meters for precise voltage and current measurements

  • Measurement of resistance to estimate temperature

  • Rugged and educational design suitable for repeated experiments

This trainer allows students to correlate electrical power input with filament temperature and verify Stefan-Boltzmann Law through calculated data. It is ideal for physics laboratories and courses involving thermal radiation, black body concepts, and electrical heating.
