Unless the electro-motive force is very great, it is not possible to obtain a spark between two metallic surfaces which are separated by a sensible thickness of air.
Lipmann further showed the reverse effect, that if a piece of mercury be forcibly pressed, so as to alter the convexity of its surface, such as by bringing it into a narrower part of the tube, then there is an electro-motive force produced.
Lipmann explained the action by showing that the electro-motive force which is generated tends to alter the convexity of the surface of the mercury.
The surface of the mercury, looked at from one side, has a convex form, which is altered by the electro-motive force set up when connection is made with the battery.
Electro-motive force is the name given to a peculiar force to which is due the property of producing a difference of potentials.
The motion shakes the gases off the electrodes, thus increasing temporarily the electro-motive force of the battery.
When it is said that zinc and water produce a definite electro-motive force, what is meant is, that by their contact a certain definite difference of potentials is produced.
The machines, on the other hand, which produce only a single light have a small internal resistance associated with a small electro-motive force.
We have only to link the cells together so that the current generated by each cell shall pass through all the others, and add its electro-motive force to that of all the others.
One of a pair of coils designed to change the voltage of a current of electricity, from a higher to a lower, or from a lower to a higher electro-motive force.
Ohm's definition of electro-motive force, current strength and resistance eventuated into Ohm's law.
It must be remembered that the volt is the practical unit of electro-motive force.
The greater the electro-motive force, the higher the velocity.
The speed at which the car runs depends upon the force that impels the current through the wire, and which is called electro-motive force.
The unit of electric induction; the induction in a circuit when the electro-motive force induced in this circuit is one volt, while the inducing current varies at the rate of one ampère a second.
The third method consists in charging a number of Leyden jars by a storage battery and in discharging these one after another, so as to obtain a high electro-motive force.
Any sudden change of the battery current produces an electric pressure or electro-motive force at the ends of the fine coil of wire.
By this simple arrangement of two coils we can thus exalt a current of low pressure to one of high electro-motive force.
Defn: The unit of electric induction; the induction in a circuit when the electro-motive force induced in this circuit is one volt, while the inducing current varies at the rate of one ampère a second.
Defn: One of the larger measures of electro-motive force, amounting to one million volts.
Here was exerted his 'Electro-motive force,' which tore the combined electricities asunder and drove them as currents in opposite directions.
This counter-electro-motive force, which develops while the machine is in motion, makes it unnecessary to hold back the current longer by the extra resistance of the rheostat and hence that is usually cut out.
In any circuit, current in webers = electro-motive force in volts / resistance in ohms.
In the whole of a circuit=current in webers x electro-motive force in volts / 746.
Electro-motive force of A pair of copper-iron junctions at a difference of temperature of 1 deg.
It is thus induced to perform the largest amount of work with the smallest electro-motive force.
The depolarising power of the manganese oxide is used to the best advantage, and that, owing to this, the electro-motive force of the battery is kept at the same point.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "motive force" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
