A dielectric is inserted between the plates of a capacitor. The system is charged and the dielectric is removed. The electrostatic energy stored in the capacitor is
1. greater than
2. the same as
3. smaller than
it would have been if the dielectric were left in place.
U= 1/2 (K)[tex]E[/tex]Ad E^2
K= dielectric constant
[tex]E[/tex]= 8.85X10^-12
i would think that when the dielectric is removed that the electrostatic energy stored in the capacitor would be smaller than when the dielectric is in the capacitor assuming that K>1? but i have been informed that my thinking is incorrect. Any help would be appreciated.
