Electric Field in a Capacitor with a Dielectric
A parallel-plate capacitor with plates of area A and separation d is charged to a total charge Q and then disconnected from the battery. A dielectric with a constant κ = 3 is subsequently inserted, completely filling the space between the plates. How is the electric field between the plates affected?
A
It remains the same
B
It decreases by a factor of 3
C
It increases by a factor of 3
D
It decreases by a factor of 9
