Two parallel-plate capacitors C₁ and C₂ are connected in parallel to a 12.0 V battery. Both capacitors have the same plate area of 4.00 cm² and plate separation of 2.65 mm. However, the first capacitor C₁ is filled with air, while the second capacitor C₂ is filled with a dielectric that has a dielectric constant of 2.65. (a) What is the charge stored on each capacitor? Q₁ Q₂ = pC PC (b) What is the total charge stored on the parallel combination? pC

Two air-filled parallel-plate capacitors with capacitances C1 and C2 are connected in parallel to a battery that has a voltage of 36.0 V; C1 = 4.00 mF and C2 = 6.00 mF. (a) What is the total positive charge stored in the two capacitors? (b) While the capacitors remain connected to the battery, a dielectric with dielectric constant 5.00 is inserted between the plates of capacitor C1, completely filling the space between them. Then what is the total positive charge stored on the two capacitors? Does the insertion of the dielectric cause the total charge stored to increase or decrease?
