A capacitor in an AC circuit. What is the amplitude of the current??

1. The problem statement, all variables and given/known data

I really do not know how to approach this problem. What confuses me is that when calculating the % error I’m suppose to have a theoretical or accepted value and a measured value. So how do I determine the amplitude of the current without using the 2 curve fit equations from the lab quest.

My measured capacitance is 1.7E-6F
My working voltage measured at the start of the lab is 4.02V

2. Relevant equations

LabQuest2 data

deltaV=5.6cos(376.87x+1.31)+.074
I=.0048cos(379.57x+2.8)-6.1E-4

3. The attempt at a solution
