How was AC converted to DC before diodes were invented?
Wow, that's really interesting. Did people use this method a lot before diodes were invented?
Yes, the commutator was commonly used in early electric motors and generators to convert AC to DC. It was also used in the first practical electric power systems, known as direct current (DC) systems. However, the invention of diodes in the early 20th century greatly simplified the process and made it much more efficient.
