I am trying to understand the dynamics in the following circuit:
I have a voltage source here.
Now, I measure current at C1 and voltage at C1/R2 and the result is this:
So, what I understand so far is that the capacitor "sucks in" all the voltage, so that the voltage that I measure is really low at the beginning. At the same time, the capacitor draws in a lot of current for loading until it is full and nothing more is drawn in.
But I do not get what happens when I change resistor values. According to voltage divider rule, the capacitor gets
I_in * R2/(R2+R1) as voltage. So, I have 4/(4+1) = 0.8 in the circuit below. But when I change R2 to 1k,
R2/(R2+R1) is 0.5, so the voltage provided to C1 should be lower. This means, it should load slower. But it doesn't the simulation will show the peak of the green curve earlier instead of later.
So, question is: What are the dynamics here? How can I calculate how fast the capacitor charges?
I tried to understand this circuit by using Ohm's law and the voltage divider rule but just nothing seems to work here...
