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 (C) of a parallel-plate capacitor affected by the charge on the plates ?

C depend on the charge on the plates

C is vanished when there are plates

C does not depend on the charge on the plates

C is accumulated on one side only

How is the capacitance of a parallel-plate capacitor affected by the potential difference across the capacitor ?

C depend on the potential difference across the capacitor

C does not depend on the potential difference across the capacitor

C partially depend on the potential difference across the capacitor

C sometime depend on the potential difference across the capacitor

How is the capacitance of a parallel-plate capacitor affected by the area of each plate?

C is directly proportional to the area A of each plate

C is inversely proportional to the area A of each plate

C is partially proportional to the area A of each plate

C is fully proportional to the area A of each plate

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

How is the capacitance of a parallel-plate capacitor affected by filling the space between the plates with an insulator ?

C stable when the space between the plates is filled with an insulator, ε_r >1

C reduces when the space between the plates is filled with an insulator, ε_r >1

C increases when the space between the plates is filled with an insulator, ε_r >1

C fluctuate when the space between the plates is filled with an insulator, ε_r >1

10.

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
