Planck's Constant

In this lab, students will use a voltage–current sensor and an AC/DC electronics laboratory to measure the turn-on voltage of various colors of LEDs and then plot the turn-on voltage versus LED frequency to determine the value of Planck’s constant.

Featured Equipment

Voltage Current Sensor

PASPORT Voltage-Current Sensor

This sensor allows students to safely measure voltage and current without overload risk.

AC/DC Electronics Laboratory

AC/DC Electronics Laboratory

Facilitates electricity experiments for AC and DC. Can be used as a stand-alone with a multimeter or with PASCO sensors and software.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
