Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

As we know that capacitance of parallel plate capacitor is given as

here we know that the gap between the plates of capacitor is filled by air or vacuum

now if we fill the space between the plates by dielectric medium then we will have

so it will increase the capacitance of capacitor

Also we can see that capacitance is inversely depends on the distance between the plates of capacitor plates

So capacitance will increase if we decrease the distance between two plates

so correct answers are

D) introduce a dielectric material between the plates

E) decrease the separation between the plates

the answer is definitely c.

answer: electrons
