Decreasing current in capacitors

  1. Apr 15, 2004 #1
    In a capacitor, after it is charged and then after the switch is open, the voltage and current decreses. How does these decresing quantities affect the voltage across R, and therefore, how do they affect the current in the circuit?

    What does your circuit look like? Is the capacitor connected to a resistor after it's been fully charged?

    A picture of the circuit:

    If it is open then how can current flow it might have switch which has been connected to the resistor i.e making a RC circuit
