Question

(a) A series circuit has a capacitor of 10−5 farad,
a resistor of 3 × 102 ohms, and an inductor of
0.2 henry. The initial charge on the capacitor
is 10−6 coulomb and there is no initial current.
Find the charge q on the capacitor at any time t.
(b) Draw a phase portrait of the equivalent dynamical system that includes the trajectory
corresponding to the initial value problem in
part (a).

Answer 1

Resistor should be 3e2 -> 300 ohms

Answer 2

I will help u if u close this question here and post in physics place.

Answer 3

Will do, thanks.
