## 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?
