Electrometer sensor

A wireless electrometer measures the electrical charge and potential of charged bodies, transmitting the data to a digital laboratory system. It supports six experiments: the study of electrification by friction with the determination of the sign and magnitude of the charge, the demonstration of the law of conservation of charge upon contact of conductors, the study of charge leakage from a sharp point and the distribution of charge along the conductor, the study of electrostatic induction, the study of the shielding effect of a conductive shell - a Faraday cage, the comparison of charges from different pairs of rubbing materials. The sensor is used for activities on electrostatics in a physics course.
