Description

This lecture covers Ohm's law, which relates current density to electric field, and the concept of specific electrical conductivity. It also discusses the units and resistivity values of different materials, including conductors and insulators. The distinction between perfect conductors and resistors is explained, highlighting the negligible electric field in good conductors and the essential role of electric field in resistors.
