Homework Statement
An electronic engineer is designing a circuit in which a capacitor of capacitance of 4700 microFarads is to connected across a potential difference of 9.0V. He has four 4700 microFarads, 6V capacitors available. Draw a diagram to show how the four capacitors could be used for this purpose.
2. The attempt at a solution
I've got the answer (see the attachment), and I get it that the capacitance equals 4700 this way, but how does the voltage equal 9V like this? I don't get it. Can someone help? :(
