This is a common problem when students forget the "true" meaning of the
elements of a formula. The defining equation for the linear capacitor is
Q = CV
This can be read (and should be read) as the magnitude of the charge, Q,
(the EFFECT) that resides on either plate of a capacitive device is
directly proportional to the potential difference, V*, (the CAUSE) between
the plates and the proportionality CONSTANT is the capacitance, C, of the
device.
