Why does your Microwave waste half its Power?
The circuit inside a microwave oven is a half-wave doubler, an incredibly inefficient design. How does it work? Why do we put them in microwaves?!

Corrections:
01:32 "Utilization" would have been a better word than "efficiency." Half-wave rectifiers have a 50% utilization, not a 50% efficiency. They only utilize 50% of the provided voltage.
01:57 Phone chargers from the 1990s and early 2000s were simple transformers. Modern phone chargers are a more complicated design called an "Switch Mode Power Supply" or SMPS.
