Showing the various components responsible for heating food. At the core is the magnetron, which generates microwaves when powered by the transformer. These microwaves are then directed into the cooking chamber through the waveguide, where they interact with the food. The antenna helps distribute the waves evenly, while the cooling fan prevents overheating of components. A diode and capacitor are involved in managing electrical flow and maintaining proper microwave generation. The image also highlights the transformer's role in converting electrical voltage to the necessary level for the magnetron to operate. This comprehensive diagram provides a clear view of how a microwave oven functions.
