Chapter 5.7, Problem 1E

An RLC series circuit has a voltage source given by $E\left(t\right)=20\text{V}$, a resistor of $100\Omega$, an inductor of $4\text{H}$, and a capacitor of $0.01\text{F}$. If the initial current is zero and the initial charge on the capacitor is $4\text{C}$, determine the current in the circuit for $t>0$.
