Voltage to charge capacitor

  1. Jan 22, 2008 #1
    1. The problem statement, all variables and given/known data

    What voltage is required to store 7.50 x 10-5 C of charge on the plates of a 7.0 µF capacitor?

    i believe the equation to be: q = CV

    so V = q/C

    i've tried plugging in the numbers to this equation and don't get the correct answer. is 7.0 uF need to be converted to a more compatible number?

    thankyou.

    2. Relevant equations



    3. The attempt at a solution

    Yes, you need to work in one set of units, making any conversions that are necessary, and you need to do the right things with numeric prefixes like "micro" = 10^-6.

    Write out your equation again for us, this time including the units and prefix multiplications, and we'll see where you are.
