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

What is the voltage across the plates of the capacitor if the capacitance is 10 uF and the Charge stored is 30 uC?

0.333 V

3 V

300 V

In the capacitor, the dielectric can be made out of all sorts of ---------- materials and the plates are made of a -------------- material.

conductive, insulating

conductive, conductive

insulating, conductive

insulating, insulating

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 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

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

If the capacitance is 47μF, and the voltage difference across the capacitor terminals is 6V, then the energy stored in that capacitor is:

846×10^-6Joule

7.23×10^-3 Joule

6.76×10^-5Joule

5.94×10^-2Joule

The plates of a parallel-plate capacitor are 2.50mm apart, and each carries a charge of magnitude 80.0nC. The plates are in vacuum. The electric field between the plates has a magnitude of 4.00x10⁶V/m. What is the potential difference between the plates?

2.00x10⁴V

1.75x10^{4 P.D.}

1.00x10^-4P

1.00x10⁴V

not solvable! because capacitor has no potential difference because it should have an insulator in between.
