Question
A parallel plate capacitor is fully charged at a potential V. A dielectric with constant ? = 4 is inserted between the plates of the capacitor while the potential difference between the plates remains constant. Which one of the following statements is false concerning this situation?
1) The electric field between the plates increases by a factor of four.
2) The charge on the capacitor increases by a factor of four.
3) The energy density remains unchanged.
4)The stored energy increases by a factor of four
5) The capacitance increases by a factor of four.
4)The stored energy increases by a factor of four
5) The capacitance increases by a factor of four.
Explanation / Answer
this is false
1) The electric field between the plates increases by a factor of four.
