Of the material that was introduced?
A) 4
B) 2
C) 0.4
D) 1/4
E) None of the other choices is correct.

Question

Quizplus · Accepted Answer

The dielectric constant (k) is equal to the factor by which the capacitance increases when the dielectric material is introduced. Since the capacitance increases by a factor of 4, the dielectric constant of the material is 4.
