electromotive force

How To Use electromotive force In A Sentence

• That electromotive force acting on a dielectric produces what we call electric displacement. The World's Greatest Books — Volume 15 — Science
• Eventually, these hopes were fulfilled, and in 1863 Raoult gained a doctorate from the University of Paris, for a thesis on the electromotive force of voltaic cells.
• Fig. 4 shows two curves; the one drawn in a full line is obtained by plotting the deflection in degrees of the needle of a potential indicator as abscissae, and the corresponding electromotive forces measured simultaneously on a standard instrument as ordinates; the dotted line shows what this curve would be with an ordinary tangent galvanometer. Scientific American Supplement, No. 433, April 19, 1884
• This paper presents translating and rotating motional electromotive force of non - straight wire in uniform magnetic field.
• It is electromotive force that drives electrons through the circuit.
• Ion channels are selectively permeable to different classes of small ions; this is necessary for a channel to generate the electromotive forces needed for electrical signalling.
• The latter equation indicates that, in a current-carrying coil, an electromotive force is induced by the magnetic flux associated with the current in the coil; the magnitude of the electromotive force is proportional to the rate of current change DI/Dt. The proportionality factor is called inductance L (more precisely self-inductance). 5. Magnetic Field
• Induction linacs, linear accelerators that induce an electromotive force on ions by rapidly changing the strength of a magnetic field inside a vacuum cavity, have proven capable of producing the necessary current.
• The force that causes electrons to move around a circuit is called electromotive force.
• The law concerning the generation of electromotive force and current in a conductor that is cutting through lines of magnetic force, may be stated in another way, when the conductor is bent into the form of a loop, as in the case under consideration: Thus, _if the number of lines of force which pass through a conducting loop be varied, electromotive forces will be generated in the loop_.
