As we discussed earlier, an insulating material placed between the plates of a capacitor is called a dielectric. Inserting a dielectric between the plates of a capacitor affects its capacitance. To see why, let’s consider an experiment described in Figure \(\PageIndex{1}\).

12 Απρ 2018 · An electric field is created between the plates of the capacitor as charge builds on each plate. Therefore, the net field created by the capacitor will be partially decreased, as will the potential difference across it, by the dielectric.
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. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators.
Figure 5.2.1 The electric field between the plates of a parallel-plate capacitor Solution: To find the capacitance C , we first need to know the electric field between the plates.
1. Capacitors and Capacitance. Capacitor: device that stores electric potential energy and electric charge. Two conductors separated by an insulator form a capacitor. The net charge on a capacitor is zero. To charge a capacitor -| |-, wires are connected to the opposite sides of a battery.
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. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators.
Figure 18.31 shows a macroscopic view of a dielectric in a charged capacitor. Notice that the electric-field lines in the capacitor with the dielectric are spaced farther apart than the electric-field lines in the capacitor with no dielectric.
