Concept

Problem: Which of the following will increase the capacitance of a parallel-plate capacitor?Check all that apply.a) Increasing the area of the plates will increase the capacitance of a parallel-plate capacitor.b) Decreasing the area of the plates will increase the capacitance of a parallel-plate capacitor.c) Decreasing the separation between the plates will increase the capacitance of a parallel-plate capacitor.d) Increasing the separation between the plates will increase the capacitance of a parallel-plate capacitor.

FREE Expert Solution

For a parallel-plate capacitor, capacitance is:

C=ε0Ad

Therefore, capacitance is proportional to the area of the plates, A. 

Capacitance is inversely proportional to the separation between plates, d. 

Therefore:
