unit 2 to 3.1

• a fundamental concept in electromagnetism.

• It measures how much an electric field “flows” through a given area.

• Imagine it as the flow of invisible lines of force (similar to water flow) passing through a surface.

• These electric field lines originate from positive charges and terminate on negative charges.

is defined as the total number of electric field lines passing through a surface per unit time.

Electric Flux:

It refers to the “rate of the flow of the electric field,” as

determined by _____

passing through a given region.

Electric flux is the property of an electric field relating to

the measure of its _____.

Gauss's Law states that the total electric flux through any closed surface is proportional to the total electric charge inside the surface.

Electric field lines always emerge from a positive charge

and end at a negative charge.

A _____ within a region will have an outward

electric flux passing through its surface.

A _____ will have an inward electric flux

through its surface.

A region containing a _____ has “no net electric

flux” passing outward or inward.

The net electric flux going

outward the surface of the

region is _____ to the

magnitude of the net charge

enclosed by that region.
