JOSBY Coulomb Torsion Scale Coulomb’s Law, High School Physics Lab Educational Teaching Equipment, Electricity Static Charge Measurement, Wheel Demonstrator Experimenter, Coulomb’s Law Demonstrator

Features

• This product is mainly composed of micrometer, suspension wire, small simplified body, large cylinder, damper, three-legged iron frame and other parts.
• The force between the two points of charge is inversely proportional to the square of their distance, and Added mechanical damping device to shorten the time and prevent the static charge from running into the air too much. The accuracy of the quantitative demonstration.
• Solved the difficulty of the Coulomb law demonstration experiment. The instrument can make qualitative and quantitative demonstrations by electrostatic charge distribution.
• Explain that the forces between two points of charge in Coulomb’s law are proportional to their charge.
• This instrument is mainly used for demonstration or group experiments in physical and electrical courses in secondary schools, technical secondary schools and colleges.
