Two capacitors of equal capacitance C are connected in parallel by wires of negligible resis-tance and a switch, as shown in the lefthand figure below. Initially the switch is open, one capacitor is charged to voltage V 0, and charge Q 0 = CV 0, while the other is uncharged. At time t = 0 the switch is closed.
A parallel-plate capacitor is made up of two parallel conducting plates with an insulator (dielectric) between them. An electrically isolated spherical conductor can also act as a capacitor. The measure of how much charge can be stored per unit potential difference is known as the capacitance.
To see how this happens, suppose a capacitor has a capacitance C 0 when there is no material between the plates. When a dielectric material is inserted to completely fill the space between the plates, the capacitance increases to is called the dielectric constant. In the Table below, we show some dielectric materials with their dielectric constant.
Compute the electric potential difference ∆V. Calculate the capacitance C using C = Q / | ∆ V | . In the Table below, we illustrate how the above steps are used to calculate the capacitance of a parallel-plate capacitor, cylindrical capacitor and a spherical capacitor. Now we have three capacitors connected in parallel.
A parallel-plate capacitor of area A and spacing d is filled with three dielectrics as shown in Figure 5.12.2. Each occupies 1/3 of the volume. What is the capacitance of this system? [Hint: Consider an equivalent system to be three parallel capacitors, and justify this assumption.] Show that you obtain the proper limits as the dielectric constants
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 .
