Question
Which of the following best describes the workings of a dielectric inside a capacitor?
Even when dipoles are induced, only existing dipoles align with the existing electric field. This results in surface charge on each dielectric surface producing an electric field in the opposite direction. This results in a decrease of the potential difference being required to place the same amount of charge on the plates, which leads to a higher capacitance, as expected.
Either existing dipoles or induced dipoles align with the existing electric field. This results in an induced surface charge on each surface, which amounts to an increased effective
charge. Since charge and capacitance are directly proportional, this leads to the increase in capacitance observed when dielectrics are inserted
Even when existing dipoles are present, only induced dipoles align with the existing electric field. This results in surface charge on each dielectric surface producing an electric field in the opposite direction. This results in a decrease of the potential difference being
required to place the same amount of charge on the plates, which leads to a higher
capacitance, as expected.

Explanation / Answer
Answer is A
Even when dipoles are induced, only existing dipoles align with the existing electric field. This results in surface charge on each dielectric surface producing an electric field in the opposite direction. This results in a decrease of the potential difference being required to place the same amount of charge on the plates, which leads to a higher capacitance, as expected.
