1. The problem statement, all variables and given/known data Plot I_r vs. time and Q_c vs. time starting from when the switch is moved from its lower position to its upper position. Label both axes with numbers and units. Show three time constants. Assume that the capacitor is initially uncharged. After the circuit reaches its final state the switch is moved to its lower position. Plot both I_r and Q_c vs. time starting from when the switch is first closed to it lower position. Again show numbers, units, etc. How long will it take for the capacitor to be 50% discharged? 90%? 2. Relevant equations Charging circuit .... q = Q_f - Q_f * e^-t/RC Discharging Circuit q = Q_o * e^-t/RC 3. The attempt at a solution I'm assuming that where the switches are drawn to be the "Lower position" so this is the moment right after the switch is flipped. Since the question states the capacitor initially is uncharged, For all 4 circuits the graph of I_r and Q_c vs time would look like I_r - starts at the max value and exponentially decays Q_c - starts at 0 and exponentially grows Right? Because the capacitor has to charge before this whole process gets to its "final state" and begins to discharge...or am I off here?
