Newton’s / Coulomb’s Law Demonstration
Study the concepts of Newton′s and Coulomb′s laws with this apparatus.This apparatus can be used to demonstrate repulsion, attraction of charged bodies and provides the ability to measure the angle between the 2 strings and thus the force between the two charged spheres. The charge can be provided by a Wimshurst machine or a Van de Graff generator or by simply rubbing a plastic rule with on a duster. Includes manual.

Analog To Digital Converter
The ADC unit converts an analog signal to digital signal. When a variable voltage is applied to the input terminals it is converted into a digital output. Therefore, a 3 volt input will correspond to binary 11, and 7 volt will correspond to binary 111. A low frequency AC input signal can be converted into a changing digital value. Use on its own or combined with the DAC to decode back into a stepped analogue voltage.
