Electric Flux

Flux

means “flow” in latin

Flux

Amount of something as it passes through a particular region or area

Electric Flux

Rate of the flow of the electric Field

Electric Flux

Determined by the number of electric fields or flux lines passing through a given region

Electric Flux

Property of an electric field relating to the measure of its strength.

Negative (inward)

When they are directed into a closed surface

Positive (outward)

When they are directed outside of a closed surface

positive charge.

Electric field lines always emerge from a _____

positively

A _______ charge within a region will have an outward electric flux passing through its surface.

negative

  A _______charge will have an inward electric flux through its surface.

electric flux

A region containing a zero charge, such as both positive and negative charges with equal magnitude are contained therein, will have “no net _______ ____” passing outward or inward.

zero

A region containing a ______ charge, such as both positive and negative charges with equal magnitude are contained therein, will have “no net electric flux” passing outward or inward.

magnitude

A region containing a zero charge, such as both positive and negative charges with equal _______ are contained therein, will have “no net electric flux” passing outward or inward.

Charges, Electric field, and Electric flux.

Electric Flux demonstrates the relationship between

+ / positive

The net electric flux going outward (_) the surface of the region is directly proportional to the magnitude of the net charge enclosed by that region.

directly proportional

The net electric flux going outward (+) the surface of the region is ______ ________ to the magnitude of the net charge enclosed by that region.

Symbol for flux/capital Greek letter phi

(Φ)

Subscript E

indicates that we are calculating electric flux

Nm²/C or Newton meter squared per coulomb.

The SI unit for electric flux is
