This ability is used in capacitors to store electrical energy by sustaining an electric field. When voltage is applied to a capacitor, a certain amount of positive electric charge (+q) accumulates on one plate of the capacitor, while an equal amount of negative electric charge (-q) accumulates on the other plate of the capacitor. It is defined as:
The electric field in a capacitor is an important parameter in the design and operation of capacitor-based circuits. It is used in the calculation of capacitance, energy storage, and the design of various electronic devices such as:
You can generate electric field and (eventually) light with capacitor. But required frequency for visible light is extremely high - c/650nm = 461Thz, way out of reach of current electronics. But if you can live with very far IR (100um and more) - it can practically be generated that way with current state of electronics.
Electromagnetism is a science which studies static and dynamic charges, electric and magnetic fields and their various effects. Capacitors are devices which store electrical potential energy using an electric field. As such, capacitors are governed by the rules of electromagnetism.
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.
