Homework Statement
In an oscillating LC circuit, L = 2.93 mH and C = 3.21 μF. At t = 0 the charge on the capacitor is zero and the current is 2.14 A. What is the maximum charge (in C) that will appear on the capacitor?
Homework Equations
I know that for an LC Circuit, the charge q at a given time t is:
q = Q cos(wt + phi)
The Attempt at a Solution
At t = 0, q = 0;
Thus,
0 = Q cos(phi),
which implies Q = 0.
So the maximum charge is 0.
However this is not right.
Any help please?
