Dielectrics: Two Capacitors, C₁ and C₂, Are Connected in Series

Multiple Choice

Dielectrics: 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?

A) The charge on C₂ increases.
B) The charge on C₂ decreases.
C) The charge on C₂ remains the same.
