Summary of Why does your Microwave waste half its Power?

00:00:00 - 00:10:00

This video discusses why microwaves waste a lot of their power. The author explains that it is because the magnetron's load creates its own waves that counteract the shift that the microwaves need in order to function properly. The author also discusses how a half wave rectifier can be used to save power.

• 00:00:00 The author of the video explains that the power supply for a microwave oven is incredibly simple, consisting of just a magnetron, a transformer, and a capacitor. The transformer is designed to turn 120 volts into 2 000 volts, which is extremely dangerous. If the microwave oven is plugged in, unplug it immediately if the probe is burned.
• 00:05:00 In this video, the author explains why a microwave wastes half its power, and how a half wave rectifier (a device that turns AC into DC) can help. The author also demonstrates how to create a half wave rectifier using a capacitor, diode, and resistor. Finally, the author shows how the waveform on the scope is shifted when the capacitor is in the wrong direction.
• 00:10:00 This video discusses why microwaves waste a significant amount of their power, and offers tips on how to save power. It discusses how the microwaves' waveform is shifted so that it has a higher voltage peak, which is not very useful. It also discusses how the magnetron's load creates its own waves that counteract the shift, and how this can cause problems with the microwaves' frequency.
