The term, 'displacement current' describes the way in which the dielectric's __________ whenever the potential-difference across a capacitor's plates changes
A) leakage current changes
B) atoms' electron orbits polarise

Question

Quizplus · Accepted Answer

When the potential-difference across a capacitor's plates changes, the electric field in the space between the plates changes. This changing electric field causes the electrons in the atoms of the dielectric to shift slightly, creating a temporary polarization of the dielectric material. This polarization leads to the displacement current. Therefore, the correct answer is B - atoms' electron orbits polarize.
