Study route
Electrical charge
- Electric charge determines the particle and body participation in electromagnetic interaction. The same-name charges are pushed away, the different ones are drawn.
7.2. Electrical field
- The electric field exists around the charges and operates on other charges. The voltage shows the force at the single positive test charge.
7.3 Wiring and dielectrics
- The conductors have hosts that can travel all over the volume, and the dielectrics have charges connected to atoms and molecules, so the material reacts differently to the outer field.
