Nettet13. apr. 2015 · In 1839, Joule performed a series of experiments in which he discovered two electrical energy relationships, though he made no claim to originality. Firstly, he noted that the power output from his electric motor was proportional to the product of the current and the electromotive force. doi 10.1136/bmj.h5863NettetEnergy units are often used in relation to environmental protection, energy reserves and geopolitics.
