Used with 274500 Insulated cups to confirm Joule’s law. Plastic lid with hole for inserting a thermometer. Fitted with 2.2 ohm heating element connected to 2 telephone jack sockets.
Determines the current through the sensor by measuring the voltage across the internal resistor.
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.
The Stress Strain Apparatus lets students observe stress and strain as they stretch a material to the point of fracture.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Allows students to mount Rotary Motion Sensors to the Rotating Platform or Gyroscope.
