Objective
We describe here the form to make two simple electroscopes that will be useful to detect the electrical charge to us of other equipment that we described in estea same webpage. The electroscopes serve to show the presence of static electricity. Normally they consist of a coductor in one of whose metallic ends two have been placed delgadaa láminaa that separate when receiving electrical charge of smimos the sign. Whichever major is the load, major will be the separation of laminae.

As They are constructed

Electroscope of light bulb to drink soda water (Electroscope of Fischer)

D - metallic disc with edges without edge
MM - heavy wire knits in D and is fitted in a rubber cork or cork piece of R);
ab - Pin that for of axis that knits to the wires;
hh - light bulb to drink soda waters;
Q - graduated quadrant, (obtained of a transporter). We notice that one subjects in an end in the cork with the help of glue and the other with a wood rod.

Electroscope of Braun

This electroscope known as electroscope of Braun, consists of a square support made of brass or another metal. In the drawing the dimensions occur to make this support. Eyelashes to soon be able are due to let some to insert in them some pieces of thin glass or plastic transparency of 12 xs 12 cm that will serve to protect the set. To the center it must have an orifice that will lodge a pl'stico piece pvc or a rubber piece. This subject one to the set of the sphere of copper, wires and light bulb to drink soda water.

For queambosl equipment work correctly, the light bulb is due to make driver of the electricity and for this it must recubiri with a “painting? made with graphite in dust and glue of white tail.

Operation

When approaching any object loaded with static electricity, or to the sphere or the disc of equipment, will notice that the light bulb moves in a certain direction.
