Consider the RC circuit shown at the figure where
Given: C = 3.60 μF, V= 16.5 V, R1 = 3.50 MΩ, R2 = 6.80 MΩ, R3 = 8.10 MΩ, R4 = 8.30 MΩ, R5 = 5.90 MΩ, R6 = 8.90 MΩ, R7 = 8.20 MΩ, R8= 2.00 MΩ.
Notice that one only needs to move the switch from connecting to a to connecting to b in order to go from charging the capacitor to discharging the capacitor.
A) Through what resistance, in MΩ, does the capacitor charge?
B) Through what resistance, in MΩ, does the capacitor discharge?
C) When discharging, does the current flow through the circuit in a clockwise (CW) or a counterclockwise (CCW) direction?
D) What is the time constant, in seconds, for charging the circuit?
E) What is the time constant, in seconds, for discharging the circuit?
F) If the capacitor is initially fully discharged, how much charge, in μC, will be on the capacitor after it has been charged for 15.0 seconds?
G) What will be the current, in micoramps, in the circuit at this time?
H) The switch is left connected to a for a very long time so that the capacitor becomes fully charged. The switch is then flipped to b and the capacitor is allowed to discharge for 68.0 seconds, at which time the switch is switched to the middle position. What will be the final charge, in μC, on the capacitor?
I understand most of the concepts, just not how this circuit works, ie. where does C go or come from, does it connect from A to B? etc.
