The capacitance of a capacitor depends on

(i) On what factors does the capacitance of a capacitor depend? (ii) Two capacitors of capacitances 20muF and 60muF are connected in series. If the potential difference between the two eneds of the combination is 40 volt, calculate the terminal potential difference of each capacitor.
