Question

A series circuit has a capacitor of 0.1 x 10^-6 F and an inductor of 0.4 H. If the initial charge on the capacitor is 0.15 x 10^-6 C and there is no initial current, find the charge Q on the capacitor at any time t.

Answer 1

you can easily solve it by analogy of mechanical oscillation and electrical oscillation

Answer 2

replace q by x, L by m, 1/C by k, F with V

Answer 3

alright.

Answer 4

Q = Qi cosωt where ω = 1/sqrt(LC) and Qi is the initial charge
