Problem
Two capacitors of capacitances 8μF and Cx are to be connected in series so that the combination has an equivalent capacitance of exactly 3μF.
(i) Calculate the value of the unknown capacitance Cx.
(ii) The series pair obtained in part (i) is connected across a 90V d.c. supply. Find the charge on each capacitor and the potential difference across each.
(iii) If both capacitors are rated for a maximum working voltage of 50V, state with proper calculation whether either capacitor will be subjected to a voltage exceeding its rating.
