BRAINBOX - YOUNG ELECTRICAL ENGINEER IDEAS & ACTIVITIES

Have you ever wondered about how waves work, and what the difference is between how a sound wave and a light wave travel?

The Triboelectric Effect provides a number of safe, quick and easy easy experiments to help students understand electrical 'charge'.

The polarity and strength of the charges produced differ according to the materials, surface roughness, temperature, strain, and other properties.

The triboelectric effect is not very predictable, and only broad generalizations can be made
