Electricity

SPECIAL WEB PRICE! For introductory electrostatics experiments as well as for indication of DC and AC voltages; suitable for shadow projection. Complete with detachable capacitor plate and stand.

Ideal low voltage power supply that can be used with low voltage illuminators such as the ray projectors in both the BlackBoard Optics™ basic and accessories sets. The voltage can be adjusted from 2 to 12 volts by simply positioning the bananna clips between the desired quantity of voltage.

Standard cathode ray tubes for oscilloscopes are poorly suited for demonstrations because important sections of the tubes are electrostatically and magnetically shielded, thus concealed from the view of the observer. Furthermore, these conventional cathode ray tubes require high accelerating...

The specific electron charge e/m can be determined quantitatively with this tube. A spherical chamber contains an electron beam system consisting of an indirectly heated oxide cathode, a perforated anode, and a Wehnelt cathode. The chamber also contains neon at a residual gas pressure of...

Designed to include all necessary materials, components and stand equiptment to perform over 30 electricity experiments.
