Question
A large capacitor of 3000 µF is charged by a constant current. After 1 minute it reaches a voltage
of 100 V. At that voltage, the charging circuit is disconnected.
a) Calculate the charging current.
b) A second identical capacitor is connected across the capacitor, using wires with 1 kΩ resistance. Sketch a graph of the voltages on the two capacitors as a function of time, with
appropriate numbers and units marked on the axes.
