Make a Simple Galvanoscope Now let's make a meter that is a little more practical to use.
A refinement of the galvanoscope is today's galvanometer.
Demonstrations You Can Give Show others how your galvanoscope can detect: whether a battery is producing current, which way the current is flowing, and whether a current is strong or weak.
Connect the coil to your galvanoscope as shown in Figure 8.
Broadly speaking, a galvanoscope is an instrument that detects the presence of electric currents.
On account of the peculiar arrangement of the legs, the galvanoscope can be made to stand firmly, even upon uneven surfaces.
Although some of the pairs of metals furnished so weak a current that it was necessary to use the astaticgalvanoscope to study the current, all produced some current, and from the results can be formed an electromotive series (ยง 301).
In case G V is not delicate enough to show clearly which way the current passes, use the astatic galvanoscope in its place for such combinations.
The astatic galvanoscope is not needed; in place of it provide a short piece of metal, such as a battery-plate, or even a jack-knife.
The galvanoscope gives us an instrument with which we can study, more fully, cells, currents, etc.
The uses of the astatic galvanoscopewill be studied more fully in later experiments.
Imagine that vibrations in the air caused by the voice are strong enough to give M a slight motion to and fro, and you can see how a current would be sent through the galvanoscope by speaking against M.
As soon as the liquids have soaked into P C the cell will be ready for use; but it is better to connect it with the galvanoscope at once and note the increase of current during the first few minutes while the liquids soak through P C.
To place the coil= in the N and S line, simply swing the galvanoscope bodily around, at the same time looking down upon the needle, until the length of the needle becomes parallel to the coil-support.
The galvanoscope and electro-magnet do not respond equally to all currents, and this is also true, even to a greater extent, with the calorimeter.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "galvanoscope" in a variety of sentences. We hope that you will now be able to make sentences using this word.
