I am having troubles determining when a capacitor is being charged or being discharged, never understood the concept when a capacitor is under going that process besides the fact when a Source is connected to a cap it will charged to said source, and once removed it will start discharging.
I am talking about more complicated circuit such as ones below.
Circuit Diagram: being questioned
Positive Cycle Analysis :
Negative Cycle analysis
I understand the positive cycle is charging the capacitor through R1, and R2, however for the negative Cycle I have no idea what that capacitor is doing? I am not even sure if this analysis is right, but this is the only thing that makes sense to me.
This is suppose to be a rectifier circuit, where it charges on every cycle I guess? So maybe the negative cycle is charging the cap as well, but when is it being discharge?
I guess what I am trying to ask if that if a cap is charging or discharging How do one find the path it takes to be charged/discharge.
EDIT: With a bit more thinking I figured the capacitor is both charging and discharging in the same cycle both postive and negative. I am still confused on which path current takes for discharging, and charging. For example if you look at the positive cycle and its discharging, is the current flow opposite and if so does that make the diode forward bias again thus changing the topology of the circuit?
