Answer:
Increasing the area of the plates will increase the capacitance of a parallel-plate capacitor.
Decreasing the separation between the plates will increase the capacitance of a parallel-plate capacitor.
Explanation:
The capacitance of a parallel-plate capacitor is given by
[tex]C=\frac{\epsilon_0 A}{d}[/tex]
where
[tex]\epsilon_0[/tex] is the vacuum permittivity
A is the area of the plates
d is the separation between the plates
We notice that:
- The capacitance is directly proportional to A, the area of the plates
- The capacitance is inversely proportional to d, the separation between the plates
Therefore, the correct statements are:
Increasing the area of the plates will increase the capacitance of a parallel-plate capacitor.
Decreasing the separation between the plates will increase the capacitance of a parallel-plate capacitor.
Answer:
It is NOT C. It is directly proportional, so the capacitance decreases as the distance increases.
