Voltage is divided up in a capacitive DC voltage divider according to the formula, V=Q/C. Therefore, voltage is inversely proportional to the capacitance value of the capacitor. So, the capacitor with the smaller capacitance will have the greater voltage, and, conversely, the capacitor with the greater capacitance will have the smaller voltage. ...
