Peak Voltage across a capacitor.

Homework Statement

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/XC = 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 text book is less than useful.

Any help would be appreciated. Thanks!

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