Description

In the experiment P2.3.4.3, the equivalence of electrical energy Eel and thermal energy Eth is established experimentally. The supplied electrical energy Eel is converted into heat Eth in the heating coil (or heating spiral). This leads to a temperature rise in the calorimeter (or water, in which the heating spiral is immersed). As the current I and the temperature ϑ are measured simultaneously as functions of the time t, the constant voltage U being known, the two energy forms can be registered quantitatively in units of wattsecond (Ws) and Joule (J) so that their numerical equivalence can be demonstrated experimentally:
Eel = Eth.
