Homework Help: Two capcitors connect in parallel, calculate V

  1. Jun 17, 2012 #1
    A 40μF capacitor and 20μF are in parallel. With 12V.
    Calculate total capacitance and V on each capacitor

    Q=CV E=1/2CV^2 Ct=C1+C2

    I don't know where to go from here, calculating total capacitance is easy enough. Don't know how to to calculate V on each capacitor however.

    Any help would be appreciated.

    Welcome to PF!

    Hi D.J Falcon! Welcome to PF! :smile:

    (try using the X2 button just above the Reply box :wink:)

    If they're in parallel, isn't V the same? :confused:

    Yeah, of course. Perhaps I was thinking of capacitors in series?
    Anyway, thanks for the help. :smile:
