Chapter 3.7, Problem 15P

In Problems 11 through 16, the parameters of an RLC circuit with input voltage E(t) are given. Substitute $I_{\text{sp}}\left(t\right)=A\cos \omega t+B\sin \omega t$ in Eq. (4), using the appropriate value of $\omega$, to find the steady periodic current in the form $I_{\text{sp}}\left(t\right)=I_{\text{0}}\sin \left(\omega t-\delta \right)$ .

$R=100\Omega ,L=2\text{H},C=5\times {10}^{-6}\text{F;}E\left(t\right)=110\sin 60\pi t\text{V}$
