Capacitor with and without dielectric medium between the plates
Capacitors make use of dielectric to insulate the two metal plates of the capacitor. The use of dielectric increases the capacitance of the capacitor and makes it more effective. Parallel plate capacitors have electrodes and insulating material that is arranged in parallel patterns, and the dielectric is placed between them.
