The capacitance of a parallel-plate capacitor can be increased by: 

• increasing the charge 
• decreasing the charge 
• increasing the plate separation
• decreasing the plate separation 

With respect to the capacitor, which relationship is true? •

• C = Q×V

• V = C×Q

• V = Q/C

• Q = C/V

How is the capacitance of a parallel-plate capacitor affected by the distance between the plates ?

• C is directly proportional to the area A of each plate

• C is inversely proportional to the distance d between the plates

• C is partially proportional to the area A of each plate

• C is not affected by the area A of each plate

If C is the capacitance in Farads, ϵ permittivity of the dielectric, A area of plate overlap in square meters and d distance between plates in meters, then:

• C = ϵd/A 
• C = A/ϵd
• C = ϵA/d
• C = d/ϵA

Is it correct to say that the capacitance is inversely proportional to the area of the parallel plates?

• True

• False

The following are factors affecting capacitance, except.

• Dielectric in between the metal plates
• Area  of the metal plates
• Distance of separation of the metal plates
• Voltage across the metal plates
