Why would voltage stay the same when a dielectric is introduced?

I need an explanation for question 6. Why would voltage stay the same across capacitor 3?


The dielectric increases capacitance which is inversely related to voltage correct? The equation Q=CV says this. So shouldn't voltage decrease across capacitor 3?

How do you get the voltage of C3 in the original set-up? How does the dielectric change all capacitance?

Yes the capacitance does increase but it does so for all three capacitors.Take another look at the question.


Hello ehild.You just beat me to it.
