Chapter 22 Current Electricity
Power measures the rate at which energy is transferred.If a generator transfers one joule of kinetic energy to electric energy each second, it is transferring energy at the rate on one joule/s, or one watt.The power or energy delivered to the motor per second, is represented by the equation:Power

COMMENTS
Joule’s experiments led to Kelvin’s statement of the first law of thermodynamics. Both work and heat represent transfers of energy into or out of a system. If energy is added to a system either as work or heat, the internal energy of the system increases accordingly.
This document summarizes a laboratory experiment on the Joule-Thomson effect. The experiment measured the temperature change of carbon dioxide gas as it underwent adiabatic expansion from high to low pressures.
James Prescott Joule (1818-1889) recognized that \(\pi_T\) should have units of pressure (Energy/volume = pressure) and designed an experiment to measure it. He immersed two copper spheres, A and B, connected by a stopcock. Sphere A is filled with a sample of gas while sphere B was evacuated.
This document discusses the first law of thermodynamics. It provides: 1) An overview of the first law for closed and open systems, including Joule's experiment that established the law. 2) Key concepts such as the steady flow energy equation, throttling devices, nozzles, and diffusers.
In Joule's original experiment, there was a cylinder filled with gas at high pressure connected via a stopcock to a second cylinder with gas at a low pressure – sufficiently low that, for the purpose of understanding the experiment, we shall assume the second cylinder to be entirely empty.
The Joule-Thomson effect is used in the Linde method for cooling and ultimately liquefying gases. For most gases, the inversion temperature is higher than room temperature, so that cooling starts immediately.

2.8: The Joule Experiment. Page ID. Patrick Fleming. California State University East Bay. Going back to the expression for changes in internal energy that stems from assuming that U is a function of V and T (or U(V, T) for short) dU = (∂U ∂V)TdV + (∂U ∂T)VdT. one quickly recognizes one of the terms as the constant volume heat capacity, CV.
Joule conducted a series of experiments which showed the relationship between heat and work in a thermodynamic cycle for a system.
