Stefan Constant Kit

Stefan Constant Kit

Product Code : JA-PLE-7961

The Stefan Constant Kit (SKU JA-PLE-7961) is a self-contained experiment set for determining Stefan's constant of thermal radiation in B.Sc and engineering physics laboratories. In this Stefan's constant experiment kit, electrical power fed to a heater between two black copper radiation plates is radiated from the plates, and the steady-state temperature of the plates together with the measured power gives the total power radiated. Thermometers, meters and a power supply are built in, so no additional equipment is needed.

Specifications

The kit contains two black copper radiation plates with a heater element between them, three thermometers, a built-in power supply, and an AC voltmeter and AC ammeter with their controls, and it is fully self-contained.

Experiments with the Stefan's constant kit

The kit is used for the thermal radiation practical in which students relate the electrical power supplied to the heater to the heat radiated per unit area of the black plates at their steady absolute temperature, as described by the Stefan-Boltzmann law.

  • Determination of Stefan's constant from the power input and the steady-state plate temperature
  • Measuring heater power with the built-in AC voltmeter and AC ammeter
  • Recording the rise to steady-state temperature with the three thermometers
  • Heat and thermal radiation practicals in B.Sc and engineering physics courses

Frequently asked questions

What does the Stefan Constant Kit contain?
Two black copper radiation plates with a heater element in between, three thermometers, a built-in power supply, an AC voltmeter, an AC ammeter and their controls.

Is any additional equipment needed?
No. The kit is self-contained and needs no additional equipment.

How is heat loss from the heater limited?
There is practically no loss of heat from the heating element by conduction, convection or radiation, so its heat energy is transferred to the plates; the heater efficiency is nearly one.
