## Homework Statement

An LC circuit includes a 0.025[tex]\mu[/tex]F capacitor and a 340[tex]\mu[/tex]H inductor.

(a)If the peak voltage on the capacitor is 190 V, what is the peak current in the inductor?

(b)how long after the voltage peak does the current peak occur?

## The Attempt at a Solution

I've solved part (a) already and it is 1.60A

Part (b) is where I'm stuck, but it's probably a joke.

I've figured the angular frequency out and we can find the period from that -->

T = [tex]\frac{2\pi}{w}[/tex] = 1.83[tex]\mu[/tex]s

However, since there is a 90 degree difference between peak voltage and current, and there are 360 degrees in a period, I'm just dividing the value of T i have by 4 to get the time to cover one quadrant. Is this the right approach or am i off?
