9 The unit of the two electrical quantities electromotive force (e.m.f) and potential difference (p.d.) is the unit (V). (a) State one other similarity between e.m.f and p.d. [U] (b) State one difference between e.m.f and p.d. [U] (c) A battery consists of four cells...
Electromotive Force of a source is the ability of the source to generate electrical energy from other forms of energy and supply it to the circuit whereas potential difference across a part of a circuit or device, measures the ability of the device or part of a circuit at converting electrical...

Solute-solute potential of mean force for non-polar molecules in water A recently proposed extension of the Pratt-Chandler (PC) theory of the hydration of non-polar solutes has been applied to the calculation of solute-solute radial distribution functions, gaa(r)s. The difference between results...
voltage Voltage(电压) is electromotive force, or difference in electrical potential, expressed in. Albert Einstein was the first man to realize the vast___of energy locked in the atom. Einstein was also the first to show in theory how the energy of the atom might be released. Indeed without...
We analyze numerically the optical force and the optical potential well for trapping a circular-cylinder type object in a near zone of a light-illuminated metal slit. Our analysis is based on the finite-difference formulas of the optical force and the optical potential energy to be developed, ...

The energy source of torque generation in the flagellar motor is not ATP butproton motive force(PMF).PMFis the electrochemical potential of the proton and results in the flow of protons from outside to inside the cell. PMF consists of two different forms of energy: membrane potential, and en...
Differences between the adatom-adatom potential of mean force and the pair potential in the limit of low adatom density are illustrated through the Kirkwood equation for a two-component solid. The major difference which remains at all adatom densities arises from the adatom-substrate contribution to...
