Am I overthinking this problem?
A 15uF capacitor is connected ot a 55V battery and becomes fully charged. The battery is removed and the circuit is left open. A slab of dielectric material is inserted to completely fill the space between the plates. It has a dielectric constant of 4.8. What is the voltage across the capacitor plates after the slab is in place?
I'm thinking that I just use V = Vo/k = 55/4.8 =11.5V
This seems too easy and doesn't use the value for the capacitor.
Can anyone tell me if I'm totally off in my thinking?
