Electric Charge
In this video Paul Andersen introduces electric charge. Electric charge has been studies by humans and was generalized by scientists such as Benjamin Franklin. The amount of charge in a system is conserved but individual charges can move...

Conservation of Electric Charge
In this video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

Thermal Conductivity
In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Resistivity
In this video Paul Andersen explains how the resistivity of a material opposes the flow of charge. Conductors (like metal) will have a low resistivity and insulators will have a high resistivity. Semiconductors will have a moderate...
