Microwave oven energy balance analysis

Tema ovog završnog rada je mikrovalna pećnica i njezina primjena. Na početku rada opisana su svojstva elektromagnetski valova, magnetsko polje, električno polje i kako nastaju elektromagnetski valovi. U sklopu elektromagnetskih valova opisane su antene, mikrovalovi, Maxwellove jednadžbe i spektar elektromagnetskog zračenja. Maxwellove jednadžbe su prikazane u diferencijalnom obliku i opisane jednostavnim rečenicama. U ovom dijelu završnog rada opisano je zagrijavanje hrane pomoću mikrovalova. U drugome dijelu rada opisani su glavni dijelovi, izvedba i način rada mikrovalne pećnice. Glavni dijelovi mikrovalne pećnice su transformator, električni kondenzator, ventilator i magnetron. Ti dijelovi mikrovalne pećnice su prikazani na jednoj slici. U ovom dijelu rada je prikazana shema transformatora, električnog kondenzatora i magnetrona. Krajnji rezultat ovog rada je opisati princip rada mikrovalne pećnice i njezinu upotrebu.The theme of this final paper is microwave oven and their application. At the beginning of the paper are described the properties of electromagnetic waves and generation of electromagnetic waves. As part of the electromagnetic waves the antenna, microwaves, Maxwell's equations and spectrum of electromagnetic radiation are described. Maxwell's equations are written as differential equations and described with simple sentences. In this part of the paper is described the heating food by microwaves. In the second part of the paper are described the main parts, performance and modes of microwave oven. The main parts of microwave oven are transformer, electrical capacitor, ventilator and magnetron. These parts of the microwave oven are shown in one picture. In this part of the paper are shown the schemes of transformer, electrical capacitor and magnetron. The final result of this paper is to describe the operating principle and use of the microwave oven
