A Determination of the Stefan-Boltzmann Constant of Radiation

A new method of measuring the constant $\sigma$ is described in which the radiant energy is measured in terms of electrical input. The results of the study of various possible sources of error are discussed quantitatively. The resulting value of $\sigma$ is 5.79×${10}^{-12\mathrm{}}$ watts·${\mathrm{cm}}^{-2\mathrm{}}$·${\mathrm{deg}.\mathrm{}}^{-4\mathrm{}}$.
