Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
Electrolytic, bi-polar, 25 Volt capacitor with screw terminals, 5 cm diameter, 8 cm long. Contains 2 capacitors
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
Allows students to mount Rotary Motion Sensors to the Rotating Platform or Gyroscope.
Allows students to conduct experiments to measure the speed of light. Reflect a laser off a movable mirror into a light receiver to measure phase differences.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
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.
Measures the gas pressure in a closed or open system (container or atmospheric pressure).
Replacement torsion bands for the Gravitational Torsion Balance (AP-8215A).
Determines the current through the sensor by measuring the voltage across the internal resistor.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
Allows students to study the behavior of a physical pendulum in either harmonic or chaotic motion.
