3.1 Pre-lab In the lab on electric potential and electric field lines, you noted that charged par- ticles produce electric fields and these electric fields, in turn, act on charged par- ticles. However, you then proceeded to produce an electric field geometry using conductors held at a particular electric potential. What happened to the electric charges? Electric charge and electric potential are closely related to each other. Putting charge on a conductor raises its electric potential. It is usually much...
