If I understand well.. C2 will be charged rapidly (how fast??)... therefore after a short time the voltage drop will be equal to V=R2*Itot because no current goes through C2 anymore... if I follow this lead, this means that the capacitor holds a voltage equal to R2*Itot. So C1 will hold...
I have some progress from I(R1)-I(R2)-I(C2)=0
V(C1)=1/C1*integrate(I,dt)
V(R1)=R1*I
V(C2)=1/C2*integrate(I-I(R2),dt)=V(R2)=(I-I(C2))*R2
I(R1)=I(C1)=C1*dV(t)/dt=V/R1
I(C2)=C2*d(V-V(R1)-V(C1))/dt
I(R2)=(V-V(R1)-V(C1))/R2
Vtot=V(C1)+V(R1)+V(C2)=V(C1)+V(R1)+V(R2)
Itot=I(C1)=I(R1)=I(R2)+I(C2)
If...
Lets say I would like to apply a constant 5V on the system as input and I would like to follow step by step the circuit charging...
I would like to know what the voltage in the circuit is at each time step v(t)
Here is the circuit:

If I follow your advice, I should find the current and volage for every component
the circuit has a source of 5V
when charging:
C1 is the capacitor after the switch
R1 is the resistor after C1
R2 is the resistor in...
thanks for your reply,
I will post the full circuit with a source... but now I am confused, I had my last physics/electricity course 8 years ago and I thought kcl stands for kirchhoff circuit law which state that all incoming current should leave a node... therefore Itot=In2=Ie1 + In1=Ie2...
Thank you for your answer
the circuit is as following:
the kcl are as follows:
Utot=Un2+U(e1,n1)+Ue2
Itot=In2=Ie1 + In1=Ie2
the problem I am having is to find U(e1,n1), Un2, In1 and In2 relations because both capacitors affect the other and then I am always missing a variable...
Hello,
I have a question about RC circuit. Given this circuit
---R2---
---- R1---C1--| |----
----C2--
which is a resistor followed by a capacitor followed by a resistor in parallel with a capacitor.
I have trouble finding the...
