The purpose of a dielectric material in a parallel plate capacitor is to
A
increase its capacitance
B
decrease its capacitance
C
insulate the plate from each other
D
increase the magnetic field between the plates
Verified Correct Answer: A.
Physical Principles & Numerical Solution
A dielectric increases capacitance by becoming polarized and reducing the effective electric field between capacitor plates, allowing more charge to be stored.
