How to derive voltage from charges on a capacitor?

I built a capacitor with electromechanics (emi) physics.
Firstly a DC bias voltage is applied on the top and bottom electrodes with stationary study. Then by applying pressures on the top plate with harmonic perturbation study (Frequency-domain, perturbation) , the charges on the top electrode can be obtained in different frequencies. The capacitance can also be calculated from the emi.Q0_1/emi.V0_1. (emi.V0_1 = DC voltage value)
What I want is to derive electric voltage from the charges on the capacitor. What physics should be applied to the model. Electrical Circuit, Electric Current or Electrostatics?
Thanks!
