Peak Voltage across a capacitor.

[ReidMerrill]

Homework Statement

https://session.masteringphysics.com/problemAsset/1385140/3/36.P42.jpg

Part A
What is the peak current supplied by the emf in the figure?
Part B
What is the peak voltage across the 4.0 μF capacitor?

Homework Equations

I = V/X_C = E₀/1/2πfC = 2πfCE₀

The Attempt at a Solution

I got 25mA for part A, which is correct. I don't know how to do part B and my textbook is less than useful.

Any help would be appreciated. Thanks!

Do a search on capacitor (or capacitive) voltage divider.
