Jun, Vol. Abstract: To determine the mechanical and electric equivalent of heat, a new experimental design is presented using an electrical resistance that is immersed in a calorimeter full of water, which has been designed in the laboratory and a device that is used to make the traditional practices of equivalent mechanical heat.
These devices at same time are connected with technological measuring instruments. In this experimental process it could be confirmed the existence of the variation of temperature with respect time. Therefore, through the law of conservation of energy, it was proved that which important physical phenomena. The results obtained during the experiment were in agreement with that predicted Joule, the equivalent of 1 Cal is equal to 4.
