Homework Statement F(s) = 3/(s(s^2 +2s + 5)) Homework Equations The Attempt at a Solution I have used partial fraction using coefficients. F(s) = (3/5)s - (3/5) ((s+2)/(s^2 +2s + 5)) and reduce s^2 +2s +5 by completing the square F(s) = (3/5)s - (3/5) ((s+2)/((s+1)^2 + 4))...

i am confused on how to find the line currents when there is a line impedance in between the wye source and delta load... is it wrong to directly add the line impedance and the delta load without converting first the delta load to wye...? is there a way that i can find the line currents and...
