Estimating the Planck constant using LEDs

Access: A-Level Premium

Suitable for:

Measure LED current–voltage curves, estimate threshold voltages and use a voltage–frequency graph to estimate the Planck constant.

This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
