The name plates on electric motors indicate the amperage at full load.
The nameplate on the appliance will give the voltage required for proper operation as well as either amperage or watts.
You can convert this to watts, of course, by multiplying amperage by the line voltage.
The copper vapor through which the electricity passes in an arc has enough resistance to keep the amperage (current) low; so the arc may not blow out the fuse at all.
A certain dimmer can be used only while the amperage remains within the proper limitations.
This table is not intended to act as an accurate guide, but merely to show the amperage theoretically required with different sized pictures, to bring about the same illumination in each case.
If carbon lamps, for instance, are changed for tungsten, the amperage will be much reduced and the dimmer may not work properly.
For this reason we have, in Table I, given only the maximum dimension of the picture and have based the amperage calculation upon the area of the circle which encloses the picture.
In determining the amperage necessary to show a picture properly, the following conditions must be borne in mind, any one of which may appreciably affect the result: (1) Nature of Screen.
The lamp houses should be of such dimensions that, with the highest amperage the lamp is capable of using, the outer walls will not become excessively hot.
The heat is proportional to the square of the current and a certain amperage, with two volts back of it, will produce just as much heat in given resistance as the same amperage with several hundred volts.
No attempt should be made to operate these from any other source than a low-voltage, low-amperage battery.
Sometimes lights fed through stage pockets require to be dimmed; but it is hardly practicable to arrange dimmers for apparatus carried by traveling companies, since a dimmer must be selected with respect to the amperage it is to control.
If the same intensity of illumination is to be provided for pictures of different sizes, the amperage must vary about as: (W x 1.
While the current has greater amperage it is not of as high potential or voltage as that commonly produced by the secondary winding of an induction coil, and it cannot overcome as much of a gap.
The current produced by the mechanical generator has a greater amperage and more heat value than that obtained from transformer coils excited by battery current.
The voltage of such a cell may be normal while the amperage is very low.
The normal voltage and amperage for a given make of cell is practically the same for all.
Battery testers are made to indicate voltage oramperage and sometimes the instrument is made to indicate both volts and amperes.
A paralleled or multiple connection adds the amperage of each cell; that is, the amperage of the battery will equal the sum of the amperage of each cell.
Secondary, when the voltage and amperage of a primary current have been changed by an induction coil; 5.
The average voltage of a dry cell when new is one and one-half volts, while the amperage ranges from about twenty-five to fifty amperes according to size.
When connected in this manner the voltage of the battery is the same as that of a single cell, but the current is equal to the amperage of a single cell multiplied by the number of cells.
The voltage of a series multiple connection is equal to the voltage of one cell multiplied by the number of cells in one battery, and the amperage is equal to the amperage of one cell multiplied by the number of batteries.
Lines of workstations showed voltage and amperage values for the power buildup in the coil.
A strip-chart recorder next to him was humming away as voltage and amperage checks proceeded.
Current is supplied to the welding machine at a higher voltage and lower amperage than is actually used between the dies, the low voltage and high amperage being produced by a transformer incorporated in the machine itself.
A smalleramperage may be readily made from a larger-size wire by making a nick in it with the cutting edge of pliers, or with a knife.
Reducing Amperage of a Fuse Wire It is sometimes necessary to use an electrical fuse of smaller amperage than those at hand, and for experimental work this is often the case.
The "series" wiring gives the entire set the combined voltage of all with the average amperage of one.
The amperage of a cell depends on its size, or rather by the area of the electrodes; but the voltage is a constant one, and is not increased by the change, formation, or size of the electrodes.
If now, we had an instrument to test the voltage and the amperage, it would be found that the voltage in B is less than that in A, and also that the amperage is greater.
The result of this form of connection is to increase the voltage equal to that of one cell multiplied by the number of cells in one set, and the amperage is determined by that of one cell multiplied by the two sets.
Thus, if the voltage and amperage of any cell be known, by the proper combination of these, we can secure the required voltage and amperage to light any miniature lamp.
How to Make a a Non-Polarizing Battery [151] Bichromate batteries are very expensive to maintain and dry cells do not furnish enough amperage for some kinds of experimental work.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "amperage" in a variety of sentences. We hope that you will now be able to make sentences using this word.
