8.4: Energy Stored in a Capacitor
The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being
Capacitance Calculator
Assuming that the plates are in a vacuum, the capacitance of two plates with area A = 1 m² at a distance d = 1 mm is 8.854 nF. To find this result, follow these steps: Convert the distance in meters: 1 mm ≡ 0.001 m .
8.1 Capacitors and Capacitance – University Physics Volume 2
Parallel-Plate Capacitor. The parallel-plate capacitor has two identical conducting plates, each having a surface area A, separated by a distance d. When a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the Coulomb force. We know that ...

The Capacitance of a Spherical Conductor Consider a sphere (either an empty spherical shell or a solid sphere) of radius R made out of a perfectly-conducting material. Suppose that the sphere has a positive charge q and that it is isolated from its surroundings. We ...
Capacitance Calculator
To calculate the capacitance in a parallel plate capacitor: Assume that the plates have identical sizes, and identify their area A. Measure the distance between the plates, d. Find the value of the absolute permittivity of the material between the plates ε. Use the formula C = ε · A/d to find the capacitance C.
How to Calculate Capacitance
Step Formula Description 1 C = Q/V Identify the charge (Q) stored in the capacitor and the voltage (V) across its plates. 2 Measure Charge (in coulombs) Determine the electric charge stored in the capacitor. 3 Also, measure Voltage (in volts) Also, determine the
