Two capacitors, C1 and C2, are connected in series across a source of potential difference. With the potential source still connected, a dielectric is now inserted between the plates of capacitor C1. What happens to the charge on capacitor C2

charge on C₂ increases

Explanation:

The dielectric material is utilized to expand the capacitance of the capacitor without changing its measurements. The dielectric comprises of polar molecules which are arbitrarily dispersed at first. As dielectric is kept between the plates of a capacitor, these polar molecules polarize under the electric field between the plates of capacitor. Because of this, the net electric field between the plates of the capacitor diminishes and its capacitance increments.

The voltage source stay connected across the capacitors, hence, voltage across the capacitor remains unchanged and charge may vary. In series circuit, the charge on both the capacitors would be same. Hence, charge on C₂ increases.
