JouleUnit of energySecondScience of StatisticsThis is a new edition of a book that was published in 1999 and reviewed in Biometrics in 2000 (pp. 1290-1291). The reviewer found the book well suited for its target audience of students in pharmacy and workers in pharmacy settings, in-cluding,...
The unit of measurement for power is the Watt, which is defined as 1 Joule of work per second. So, multiplying the steady power rate in a DC circuit by the time we keep it powered will result in an answer of joules (total energy dissipated by the resistor): Work=(V2R)t Showing ...
