Homework Statement
Still can't figure this one out.
All data is on the picture attached.
I have to find the current flowing through E1 after E2 is connected and draw a graph as it changes in time of the process.
I can't do the equations when t=0
Homework Equations
dUc/dt|t=0...
its a dc circuit right after commutation, the commutator switch is closed and is in series with E2 and R1 (i replaced it with a black line in the picture).
Here i found an example, as i understand i have to calculate the currents in the exact moment when the condenser is being charged.
any help...
Homework Statement
Find current flowing through E1 ( find I1).
Homework Equations
I see 6 currents, atleast until the capacitor is charged, what i find confusing are the branches without any resistance and they seem to mess up my equations.
The Attempt at a Solution
1st kirchhoff's law...
1.My question basically is: how to get the equation of my graph.
2.So far I have discovered that this has something to do with harmonic levels, I've gotten some quite similar graphs, but still something is not right
3.I was just told that I could use some Eulers formula, but not sure which.
Homework Statement
Since the exercise has a graph I uploded it here :http://imageshack.us/photo/my-images/833/img9845wz.jpg/
fmax(t)=1 T=2Pi
h=1,3,5,7,...
Also I was told that I could use Eulers formula here.
Homework Equations
maybe someone could give me some tips how to make the...
