13. A series circuit consists of a resistor with R = 20 ohm, an inductor with L = 1 H, a capacitor with C = 0.002 F, and a 12-V battery. If the initial charge and current are both 0, find the charge and current at time t.
14. A series circuit contains a resistor with R = 24 ohm an inductor with L = 2 H, a capacitor with C = 0.005 F, and a 12-V battery. The initial charge is Q = 0.001 C and the initial current is 0.
(a) Find the charge and current at time z.
(b) Graph the charge and current functions.
The solution solves differential equations is applied to current and charge in the series RLC circuit.
