How does increasing the distance between the plates of a capacitor affect its capacitance?

When the distance between the plates of a capacitor increases, the capacitance decreases because capacitance is inversely proportional to the distance between the plates. The formula for capacitance is:

C=ε0⋅A/d​

Where:

• $C$ is the capacitance,
• ε0​ is the permittivity of free space,
• $A$ is the area of the plates,
• $d$ is the distance between the plates.

As $d$ increases, the capacitance decreases because the plates can store less charge at a given voltage.
