Answer:
Explanation:
Capacitance: It is known as the ratio of change in electric charge to the corresponding change in the electric potential.
Write the expression for capacitance of a capacitor.
Here, electric permittivity is , area of capacitor is , and the distance between the capacitor plates is .
Write the expression for capacitance of A.
Here, electric permittivity is , area of capacitor is , and the distance between the capacitor plates is .
Substitute for for .
Write the expression for capacitance of B.
Substitute for , for , and for .
Write the expression for capacitance of C.
Substitute for and for .
Write the expression for capacitance of D.
Substitute for and for .
The relative permittivity and the area of capacitor are directly proportional to capacitance, and the distance between the capacitor is inversely proportional to capacitance. As the area of the capacitor is increased, the overall capacitance is increased, and as the distance between the capacitor increases, capacitance decreases. Thus, capacitance depends on the area of the capacitor, distance between the capacitor, and the relative permittivity.
