Physically, capacitance is a measure of the capacity of storing electric charge for a given potential difference ∆ V . The SI unit of capacitance is the farad (F) : 6 F ). Figure 5.1.3(a) shows the symbol which is used to represent capacitors in circuits.
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r filled with dielectric with dielectric constant It is instructive to check the limit where κ , κ → 1 . In this case, the above expression a force constant k, and another plate held fixed.
The equivalent capacitance is given by plates of a parallel-plate capacitor as shown in Figure 5.10.3. Figure 5.10.3 Capacitor filled with two different dielectrics. Each plate has an area A and the plates are separated by a distance d. Compute the capacitance of the system.
where A is the area of the plate . Notice that charges on plate a cannot exert a force on itself, as required by Newton’s third law. Thus, only the electric field due to plate b is considered. At equilibrium the two forces cancel and we have The charges on the plates of a parallel-plate capacitor are of opposite sign, and they attract each other.
Figure 5.1.1 Basic configuration of a capacitor. In the uncharged state, the charge on either one of the conductors in the capacitor is zero. During the charging process, a charge Q is moved from one conductor to the other one, giving one conductor a charge + Q , and the other one a charge − Q .
