INSTALLATION FOR INVESTIGATION OF ELECTRIC CAPASITY OF CONDUCTORS ON THE MODEL MADE OF ELECTRIC CONDUCTING PAPER Russian patent published in 2017 - IPC G09B23/18 

FIELD: electricity.

SUBSTANCE: rectangular plate is laid on the conductive paper sheet (CPS) provided with a rectangular coordinate system in the form of mutually perpendicular lines. At the edge of the left side of the CPS sheet, the rectangular stationary electrode is set, and the right half of the CPS sheet, the rectangular movable electrode is set. Near the fixed electrode on the CPS rectangular sheet of a removable conductor of circular cross section tightly pressed against the CPS sheet by the first screw with a nut. A detachable wire with a marking and installed on a sheet of CPS and is installed on the removable conductor. The movable rectangular electrode is pressed by the second screw with a nut using a metal strip mounted at one end on the support, and the other end on a movable rectangular electrode. The potentiometer is connected to the DC source by terminal contacts, and its movable contact is connected to the first input of the ammeter. The second input of the ammeter is connected to the common contact of the first switch in two positions. The contact of the first position of this switch is connected to the fixed rectangular electrode, and the contact of the second position with a removable conductor of circular cross section. The first input of the voltmeter is connected to the negative terminal of the DC power source and a metal rail, and its second input - to the common terminal of the second switch has two positions. The contact of the first position of this switch is connected to the second input of the ammeter, and the contact of the second position is connected to the upper end of the probe.

EFFECT: expansion of the field of research.
