Microwave-oven-working-mechanism, a microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. this induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.. How do microwaves cook food? how does a microwave turn electricity into heat? like this! inside the strong metal box, there is a microwave generator called a magnetron.when you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves.; the magnetron blasts these waves into the food compartment through a channel called a ..., mechanism of a microwave oven. 1. mechanism of microwave oven 2. submitted by : afif al mamun 3. contents introduction history technical design how it works advantages health hazards.
Bill details how a microwave oven heats food. he describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the wate..., for food to be heated in a microwave oven, microwaves must pass through the food. microwaves are electromagnetic waves with a frequency of about 2.45 ghz and a wavelength of about 12.2 cm; in the electromagnetic spectrum, they fall before infrared light but after radio waves (heckert 2007)..
The microwave oven was one of the 20th century’s greatest time-saving devices invented. microwaves did not come about because someone needed to find a quicker and more convenient way to cook., if your microwave oven has failed to work or turn on as usual: 1 – be sure the microwave is plugged in 2 – make sure the gfci is not tripped on the electrical outlet 3 – check that the breaker that controls that outlet is not tripped. check and reset gfci outlet if microwave has no power. if the 3 items above have checked out, continue following the microwave repair guide below….
Repairing your microwave is easier than it seems. use our symptoms based repair guide to troubleshoot, diagnose, and fix your microwave., dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (rf) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material. at higher frequencies, this heating is caused by molecular dipole rotation within the dielectric.. Place a microwaveable safe cup, mug, or bowl of water inside the unit. press clear/off or reset to clear the keypad.. press cook and enter 60 seconds.. check the water to see if it was heated.
