But there is a type of battery made that is available for either open or closed circuit operation.
Batteries for producing electricity may be divided into two classes, called "open circuit" batteries and "closed circuit" batteries.
The Fuller cell is suitable for open and semi-closed circuit work; its electromotive force is about 2.
In closed circuit cells polarization is prevented by chemical action, so that the current will be constant and steady till the energy of the chemicals is expended.
The same condition holds good for the electric current; if in a closed circuit a constant current circulates, the same amount of electricity will pass every cross section per second.
The depolarizer will take care of a limited amount of the hydrogen produced when the cell is on closed circuit, but if the circuit be closed for any length of time polarization occurs.
As the full significance of the experiments shown by these extracts may not be apparent to a lay reader, it may be stated by way of premise that, ordinarily, a current only follows a closed circuit.
With Edison's telephone a closed circuit is used on which is constantly flowing a battery current, and included in that circuit is a pair of electrodes, one or both of which is of carbon.
Until the time of Edison's investigations of 1875, now under consideration, electricity had never been known to manifest itself except through a closed circuit.
Keep in mind the fact that the lamp will always burn on an open circuit and go out on a closed circuit.
The operation of a drop on a closed circuit is a little different from its operation on a normally open circuit.
If any currents come from the coil, later, you should be able to tell in which direction they flow, the coil and A G forming a closed circuit.
An increase in the number of lines of force that pass through a closed circuit produces an indirect induced current; while a decrease produces a direct one.
In closed circuit armatures, such as used in the continuous current systems, it is best to make four derivations from equi-distant points or bars of the commutator, and to connect the same to four insulated sliding rings on the shaft.
Between these poles is mounted an armature--for example, a ring or annular armature, wound with a series of coils F, forming a closed circuit or circuits.
In starting this motor the shunt is closed around the armature coils, which will therefore be in closed circuit.
When this connection is made, the circuit is called a "closed circuit.
This disadvantage may be entirely overcome by the adoption of a simple modification, known as the "closed circuit system" of bell ringing.
On the other hand, with the "closed circuit" system, one has merely to place the wire in any convenient position, it being better seen than hidden.
Currents of such high frequencies will oscillate, that is, surge to and fro, in an open circuit, such as an aerial wire system, as well as in a closed circuit.
I have just said in fact that an isolated element is not acted upon in the same way as a movable element making part of a closed circuit.
Now there we have in a sense a closed circuit, since the electricity describes the closed circuit BNAMB; but the two parts of this current are very different.
Since the measurement is made on closed circuit the reading does not give the total pressure of the battery.
If the active portions only be separated so that they do not form a closed circuit, it will answer the purpose.
The ends of the coil are to be connected to an astatic galvanoscope; this forms a closed circuit.
Even if the conditions were wholly static there would be polarized lines of force, in a state of strain, reaching around in a closed circuit.
In practice there are a certain number of turns and a certain sized wire that will give the best results with a given number of cells of battery (or a given voltage or pressure), operating in a closed circuit of a given resistance.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "closed circuit" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
