here I have found an example with the equations when t=0

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...

exactly

ow my bad! E2 I ment

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...
