A small capacitor of 100 pF is charged by a steady current of 1 µA for 1 ms. At that time, the charging circuit is disconnected. a) What is the voltage across the capacitor when the charging finishes? b) A 10 MΩ resistor is connected across the capacitor to discharge it. Sketch a graph of the voltage V across the resistor as a function of time, with appropriate numbers and units marked on the axes
