| Abstract: | A new method of direct measuring heat dissipating rate of heated body is introduced. Provided the heating power (exactly the voltage multiplying current) be obtained, we can get the heat dissipating rate immediately. By a newly devised special apparatus and thermal conducting formula of Joseph Fourier the conductivity of poor conductor is obtained instantly as well. Because of eliminating indirect measurement of heat dissipating rate, these methods reduce errors, simplify devices and render the experiment easy for students. Above all, they emphasize physical ideas of the experiment. |
