Example \(\PageIndex{1A}\): Capacitance and Charge Stored in a Parallel-Plate Capacitor. What is the capacitance of an empty parallel-plate capacitor with metal plates that each have an area of \(1.00 \, m^2\), separated by 1.00 mm? How much charge is stored in this capacitor if a voltage of \(3.00 \times 10^3 V\) is applied to it? Strategy
Describe the action of a capacitor and define capacitance. Explain parallel plate capacitors and their capacitances. Discuss the process of increasing the capacitance of a dielectric. Determine capacitance given charge and voltage. A capacitor is a device used to store electric charge.
The capacitance of a parallel- plane capacitor depends on its geometry and is given by: S. C = 0. d. [2] Where e0 is the permittivity of vacuum, and has a value of 8.85×10-12 C2/Nm2, S is the area of each capacitor plate and d is the distance between them.
Theoretically, the capacitance of parallel-plate capacitors is . C = ε A. P 0 / d. (4.2) where the subscript “P” denotes “parallel plate.” Here, A is the area of one of the plates, d is the distance between them, and ε0 is a constant called the “permittivity of free space,” which has a value of 8.85 × 10-12 C2 / N-m2, in SI units.
Devise (and perform) an experimental procedure to verify that a parallel plate capacitor lled with two di erent dielectrics (nylon and vinyl) placed in parallel, side by side (see Fig. 4), behaves as two separate capacitors in series. Record some values of the capacitance.
