Complete Question
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 5.30 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 2.10.
(a) What is the charge stored on each capacitor
(b) What is the total charge stored in the parallel combination?
Answer:
a
i
ii
b
Explanation:
From the question we are told that
The voltage of the battery is
The plate area of each capacitor is
The separation between the plates is
The permittivity of free space has a value
The dielectric constant of the other material is
The capacitance of the first capacitor is mathematically represented as
substituting values
The charge stored in the first capacitor is
substituting values
The capacitance of the second capacitor is mathematically represented as
substituting values
The charge stored in the second capacitor is
substituting values
Now the total charge stored in the parallel combination is mathematically represented as
substituting values
