A dielectric material such as paper is inserted between the plates of a capacitor as the capacitor holds a fixed charge on its plates. What happens to the electric field between the plates as the
Dielectric is inserted?
A) There is no change in the field.
B) The field becomes weaker.
C) The field reduces to zero.
D) The field becomes stronger.

Question

Quizplus · Accepted Answer

When a dielectric material is inserted between the plates of a capacitor holding a fixed charge, the electric field between the plates becomes weaker. This is because the dielectric material becomes polarized in the presence of the electric field, creating an opposing field that reduces the overall field strength between the plates.
