Explore how a capacitor works! Change the size of the plates and add a dielectric to see the effect on capacitance. Change the voltage and see charges built up on the plates. Observe the electric field in the capacitor. Measure the voltage and the electric field. A capacitor is a device used to store charge.
The performance of a capacitor expressed in terms of the capacitance (C) depends on the dimension/geometry of the plate/electrode and the dielectric constant of the material, where the dielectric can be defined by insulating medium having permittivity, with no AC power losses or DC leakage.
U is the electric potential energy (in J) stored in the capacitor’s electric field. This energy stored in the capacitor’s electric field becomes essential for powering various applications, from smartphones to electric cars (EVs). Dielectrics are materials with very high electrical resistivity, making them excellent insulators.
When the capacitance and leakage currents of each capacitor are identical, the voltage ratings get added up. In certain applications, the series strings are connected in parallel, which forms a matrix and the goal of doing the same is to maximize the energy storage of the network without overloading any capacitor.
In order to specify the capacitance information of a capacitor, color codes are used. Color codes are the information by which the capacitance is represented. In color coding technique, the capacitance value is marked on the body of the capacitors by using different colors. The colors painted on the capacitors body are called color bands .
The characteristics of capacitors are frequency-dependent. At low frequencies, they function as expected, however, the performance of capacitors changes at higher frequencies because of factors like equivalent series resistance (ESR) and equivalent series inductance (ESL.

Electric Field Lines: Definition, Properties, and Drawings
The electric fields at point A due to charges +q and -q are E 1 and E 2, respectively. Therefore, the net electric field at A due to the charges is E = E 1 + E 2. Similarly, suppose other points in the region are chosen (not shown in the image for simplicity). The electric field at those points can be determined by this vectorial addition method.
