here is the question
**broken link removed**
from kvl
[latex]
v_s(t)-I_LR-V_L-V_c=0
[/latex]
[latex]I_c=I_L\\[/latex]
[latex]\dot{v_c}=\frac{I_c}{c}=\frac{I_L}{c}\\[/latex]
[latex]\int \frac{I_c}{c}=v_c[/latex]
[latex]
v_s(t)-I_LR-V_L-\int \frac{I_L}{c}=0
[/latex]
[latex]
\delta (t)=I_LR+V_L+\int \frac{I_L}{c}
[/latex]
and i got to this equation
[latex]
L\ddot{I_L}+\dot{I_L}R+\int \frac{I_L}{c}=\delta (t)
[/latex]
upon what theoretical basis they say the it equals
[latex]
\ddot{I_L}+\dot{I_L}+{I_L}=0
[/latex]
