3 cards from this section. Quick, good the night before a test.
What is electric flux?
Think about field lines and a surface.
State Gauss's Law in simple terms.
Focus on the relationship between flux and charge.
What does Gauss's Law relate to?
Think about the definition of Gauss's Law.
True or False: The electric flux through a closed surface can be zero if there is an equal amount of positive and negative charge inside.
Reflect on how charges affect electric flux.
A uniformly charged sphere has a charge of +10 µC. Calculate the electric field at a point 0.5 m from the center of the sphere.
Think about how the field behaves outside a sphere.
An infinite charged plane sheet has a surface charge density of 5 µC/m². Use Gauss’s Law to find the electric field strength.
What does the formula tell you about electric fields near sheets?
