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...
first, electromotive force is the energy supplied by a battery / power source, to ''push'' the charge through a circuit right? its unit is in Volts. then, potential difference is defined as the work done to push 1 Coulomb of charge from point B back to point A. and its units is al...
In this article, you will study the concept ofelectric potential,potential difference (PD) and electromotive force (EMF)and the difference between them. Just as a body raised above the ground has gravitational potential energy, similarly, a charged body has electric potential energy. When a body ...

It was also described formally as the force necessary to separate two charges (one positive and one negative) from one another.Volts are the unit of measurement. The letter 'E' is often used to represent electromotive power (epsilon). If we define emf mathematically, we get: Where 'E' ...
electromotive force (EMF)Radio-frequency (HF) quasi-potential Φ in the field of the space charge region of contact of a metal–semiconductor is explored. At the frequency, ω, greater frequency plasma fluctuations ω0HF quasi-potential is positive, but at frequencies ω < ω0quasi-potential ...

Volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt. ...
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...
