Capacitance of parallel plates as a function of distance

  1. Apr 20, 2008 #1
    Capacitance= (permitivity x Area of overlap)/ distance between two plates

    Why is capacitance inversely proportional to the distance between two plates?

    I understand that C=Q/V. So capacitance is the amount of charge it takes to change the potential difference between the two plates by 1 volt. And another definition of capacitance is the ability to store charge.

    Hyperphysics has a good explanation here.
