1. The problem statement, all variables and given/known data
What voltage is required to store 7.50 x 105 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.
