GeRRiT Pointer Electroscope Teaching Instrument High School Physics Experiment Science Teaching Experiment Electrometer Verification Electrostatic Faraday Cylinder Physics Experiment Equipment

Feature:When measuring the potential difference between two charged bodies, connect the electroscope metal casing to one charged body, connect the metal rod to another charged body, and generally ground the casing.If the earth potential is taken as zero, the potential of each charged body can be measured with an electroscope.When testing the electrification of the object, the electroscope ball can be used to contact the object under test first, and then the obtained electric charge is transferred to the electroscope metal rod, or the metal rod is directly contacted with the object.The easiest way to test the insulation of an object, as long as the object is grounded (touch it with your hands), the other point of the object is in contact with the charged electroscope metal rod, and the electroscope pointer is observed. If the pointer quickly returns to zero, The tested object is a conductor, otherwise it is an insulator.Specification:Product name: pointer electroscopeProduct size: 102*70*335mm/4.01*2.75*13.18 inProduct weight: 650gMaterial: plastic base, metal cylinder, frosted glassPurpose: This instrument is used for electrostatic experiment, can measure the potential difference between two charged objects; check whether the object is charged; check the object's insulation is negative, and perform the test of induction electrification, etc.Package:1 * Pointer Electroscope Teaching Model
