This equation determines the electric potential energy for point charges

What is UE = kq1q2/r

(When you have multiple point charges, use this equation for each and add them all together)

107

The value of the electric field inside a conductor is always this value. (For full credit must explain why)

What is E = 0, all of the charges are on the surface of the conductor

107

This equation determines the capacitance of a capacitor.

What is C = Q/V

(from the Q = VC equation)

107

The definition of a dielectric.

What are materials that are insulating that are placed within a capacitor?

254

This equation determines the electric field of a point in space

What is E = kQs/r2

254
Electric fields of a conductor are always in this direction

What is perpendicular to the surface of the conductor?

254

This series of equations relates capacitance to the electric electric field.

What is C = Q/V, V = ∫E ·dr

E and V are directly proportional to each other, but both are indirectly proportional to C

254
The purpose of a dielectric.

What is to increase the capacitance?

329

This equation determines the electric force on a point charge

What is F = kQsq/r2

329

The charges in a conductor do this when there is a charge within a cavity in the conductor. 

What is align themselves along the edge of cavity to cancel the charge within cavity?

(E FIELD MUST ALWAYS BE ZERO IN CONDUCTORS)

329

The units for capacitance.

What are farads

329

This equation relates the capacitance of the dielectric to the original capacitance of the capacitor.

What is Cdiel = 𝜅Co

472

This equation determines the electric potential of a point charge

What is V = kQs/r

(different from electric potential energy)

472

This behavior occurs in sharp corners of conductors. 

What is the charges are more condensed in corners. 

(Because the conductor acts as an equipotential line, where there is a corner, the lines are closer together so the charges are greater and more condensed.)

472

This equation relates work to capacitance

What is W = (1/2)Q2/C = (1/2)CV2

472

When a dielectric with 𝜅 >> 1 is added to a capacitor, it has this affect on the potential difference across the capacitor.

What is causes the potential difference to decrease (because it increases the capacitance)?
