An RLC series circuit has a voltage source given by E(t) = 20 V, a resistor of 245 £2, an inductor of 7 H, and a capacitor of 0.05 F. If the initial current is zero and the initial charge on the capacitor is 9 C, determine the current in the circuit for t> 0. I(t) = (Type an exact answer, using radicals as needed.)
