(b) A student has three capacitors. Two of the capacitors have a capacitance of 4.0 µF and one
has a capacitance of 8.0 µF.
Draw labelled circuit diagrams, one in each case, to show how the three capacitors may be
connected to give a total capacitance of:
(i) 1.6uF
(ii) 10µF.
The switch S in Fig. 19-90 is
connected downward so that capaci-
tor C, becomes fully charged by the
battery of voltage Vg. If the switch is
then connected upward, determine
