Derive an expression for Joule
WebAccording to Joule's law of heating, the heat produced in the resistor is 1. Directly proportional to the square of the current through the resistor. 2. Directly proportional to the resistance of the given resistor. 3. Directly proportional to the time for which the current flows. Mathematically, Joule's law of heating is given by H=i 2Rt WebJoule heating described quantitatively is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I 2 R. The power P has units of watts, or joules per second, when the current is expressed in amperes … WebWe’ll shortly derive a more general expression for CP − CV, but the correction for nonideality will obviously be quite small. 10.3 The Joule-Thomson Experiment The experiment is also known as the Joule-Kelvin experiment. William Thomson was created Lord Kelvin. The experiment is also known as the porous plug experiment. smackdown vs raw 2008 iso
