•Resistivity -



	Ampere’s Law: Flux of mahnetic field through a closed surface is zero; therefore, there are no magnetic monopoles.

	Gauss’ Law (early 1800s): Flux of electric field through a closed surface is proportionally equal to the charge inside.

	Faraday’s Law (1831): Electrioc field is induced by a changing magnetic field (magnet in a coil experiment).

	Maxwell’s equations (mid-1800s): Unified light and electricity/magnetism.

	Ohm’s Law: A discontinuous E-field at a boundary in conductivity. Charges build at the boundaries.
