Demonstration of the existence of positive and negative charge through its separation: a) by striking PVC and acrylic glass rods against each other, b) by rubbing them against various materials. Depending on the combination, the rods charge either positively or negatively.
Demonstration of electric field lines using a suspension of small particles in oil.
Charge is distributed only on the surface of conductors. The distribution of this charge can be influenced by electrostatic induction.
The charge density on the surface of conductors varies according to the curvature of the conductor at a given point.
Coming soon.
Demonstration of the motion of charges. Coming soon.
