Study of STEFAN’S LAW
Product Code : JA-VOVLACOS-1114
The Study of Stefan's Law apparatus (SKU JA-VOVLACOS-1114) verifies Stefan's law of radiation with an ordinary 6 V filament bulb. The built-in variable power supply sets the filament voltage, a voltmeter and an ammeter read the voltage and current, and the filament resistance worked out from them gives its temperature through the resistance-temperature relation for tungsten. The power fed in is then compared with the fourth power of the temperature.
