3B Scientific UE3070400-230 Experiment: Perrin Tube, 230 V

3B Scientific, UE3070400-230, Experiment for Electricity: Perrin Tube, 230 V, 50/60 Hz

UE3070400-230 Includes Only:

• Perrin Tube S
• Tube Holder S
• Helmholtz Coils S
• High Voltage Power Supply 5 kV (230 V, 50/60 Hz)
• DC Power Supply 20 V, 5 A (230 V, 50/60 Hz)
• Kolbe's Electroscope
• Set of 15 Safety Experiment Leads, 75 cm

Features:

• Objective: Determine the polarity of the charge-carriers

In the Perrin tube, the electron beam can be deflected into a Faraday cup by applying a homogeneous magnetic field. The charge of the electrons can be observed by connecting an electroscope to the Faraday cup, and its polarity can be determined by comparison with an electric charge of known polarity.
