Using this source holder, a Risø source can be positioned precisely in the axis of rotation of the joint link.
The holder is turned from plastic, to ensure its rotational symmetry.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
LED Light Source with adjustable brightness control, for use with Millikan Oil Drop Apparatus.
Determines the current through the sensor by measuring the voltage across the internal resistor.
PASCO’s Light Sensor is ideal for indoor and outdoor relative light intensity experiments.
Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
