TESS - Training and Experiment System
Electricity/ Electronics sets with 69 experiments in physics
Phywe provides the following complementary sets of apparatus for the topic of electricity and electronics: TESS Electricity/Electronics EEP 1 and TESS Electricity/Electronics EEP 2, allowing as many as 69 experiments to be performed. The experiment literature guides students through the experiments themselves in a series of easily understood exercises.
