voltage of an ideal battery in a DC circuit? Is it work per unit the emf. The subject is discussed in detail, of course, in all standard textbooks on elec- tromagnetism, both at the intermediate [1-9] and at the advanced [10-12] level. Here .. 2.3.1/modules/document/file.php/TOM6104/EM%20Volume%20PDF.pdf (in Greek).
Objectives: After completing this module, you should be able to: •• Solve problems involving emf, terminal potential difference, internal resistance, and load resistance. •• Solve problems involving power gains power gains and losses losses in a simple circuit containing internal and load resistances. •• Work problems
Keep in mind, that EMF as the name suggests is not an electrical force, it is basically the potential difference across the terminals when the key is open i.e. when no current is drawn from the cell. EMF is named so by the scientists who performed faulty experiments and named it so, hence, just a tribute to their contribution to
Electric charge is inseparable from the mass; it has two different forms (+ve and –ve); impossible to observe directly. PD, EMF are abstract concepts. Voltage is hard to understand as students don't understand the balance of pressures and pressure differences. There are a variety of definitions of work and potential energy;
14 Jan 2011 emf is the work done by the battery force (Fb) in moving unit charge from one electrode to another. emf is due to the battery force which is not electrostatic and due to some battery mechanism. therefore it do not decrease with time when battery is in use. while potential difference is due to the charges on 2
Electromotive Force (emf) vs Potential Difference. Electromagnetism is an integral part of physics. There are terms and units which are very closely related to each other and have a very fine line distinguishing the two. “Potential difference" and “emf" are two such terms. Electromotive Force (emf). Electromotive force, or emf,
18 Sep 2012 Kirchhoff's (voltage) law states that the sum of the “voltage drops" around any loop is zero. However are, in general, neither differences in the electric scalar potential V , nor the EMF = ?. E·dl Eng. 68,. 877 (1949), physics.princeton.edu/~mcdonald/examples/EM/slepian_ee_68_877_49.pdf.
In the case of a two-terminal device (such as an electrochemical cell) which is modeled as a Thevenin's equivalent circuit, the equivalent emf can be measured as the open-circuit potential difference or "voltage" between the two terminals. This potential difference can drive an electric current if an external circuit is attached

If F n="0" > charge will flow between terminals until V ab. =0 displacement opposite to. F e > potential energy.
vd is very small around 0.1 mm s-1. Clearly, the current is proportional to drift velocity. I ? vd. For many materials, including metals, vd ? E. So I ? E. Consider a section of a conductor with cross sectional area A and length L. Let a potential difference ?V be applied between the two ends, so. L. V. E. ?. = Current: I ? E and.
