Homework Help: Another Capacitnence question

  1. Oct 17, 2005 #1
    What is the formula for finding the voltage across a capacitor?

    where V is voltage, Q is the charge, and C is the capacitance.

    Umm, if I have two in capacitors (5E-6 C and 15E-6 C) in series, and the source voltage is 15V, what would the voltage across the first one be?

    I know in parallel it would be 15, but how would you do it if they were in series?

    in series....the charge on both capacitors is the same n the sum of voltages across the 2=source voltage......now work it out
