Peak Voltage across a capacitor.

  1. Apr 7, 2016 #1
    1. The problem statement, all variables and given/known data
    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?
    2. Relevant equations
    I = V/XC = E0/1/2πfC = 2πfCE0

    3. 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.
