I had to calculate partial fractions cause my table is rubbish.
A= -6/5
B= 3/5
What to do next?
(-6/5 )/s + (3/5) (10+2s)
i(t) = -6/5 +( 3/10)e -2t
The answer should be 0.6(1-e -5t)
Could you tell me where i made mistake?
ok,
I(s)=6/ (s(10+2s))= 3/ (s(s+5))
I(t)= 3+ 3e -5t = 3(1+e -5t)
Am i right ? And what next? I think i will have to deal with partial fractions.
Is= 3/ s(s+5)= A /s + B / (s+5)
I found a very similair example, but don't know how to use my numbers. I am running out of the time now. Can you help?
The voltage, V, will be the sum of the two voltages, VR and VL. Where VR = Ri(t) and VL = L(di(t)/dt).
Thus, 6 = VR + VL = 10i(t) + 2 di(t) /dt...
Could you please help me with net impedance, i can't find equation for it? And I am stuck!Z= (R+ jwL) + (1/ ( jwC)) how can i calculate j for this equation?

I used this website to educate myself a bit more then i remembered from school www.mash.dept.shef.ac.uk/Resources/web-partialfractions.pdf
But does it matter which way i used to calculate A and B.
i(t)= 20e 1 + (-20) -2t
But what next?
