The opposite figure shows a part of a circuit in which
the current intensity that passes through it at an instant
is 2 mA, when the accumulated charge on any one of
the plates of the capacitor equals 12 uC, so the value
the potential difference between the two points a and b
at this instant
(b) 19 V
a) 3 V
c) 23 V
(d 27 V
