Thomas Edison and the Vacuum Diode
An anode is where the electrons leave, and the cathode is where the electrons come in.
If you don’t understand this, neither do I, so don’t worry.Thomas Edison! We all know him!
Or do you?
But what is a vacuum diode? How do you even pronounce that? Well, thanks to Google, just look it up.
Jk.
It’s pronounced dai-owd.
So, what even is a vacuum diode, anyway? “A diode is an electronic component with two electrodes (connectors) that allows electricity to go through it in one direction and not the other direction.” states kiddle.co.
Although the vacuum tube was invented by John Ambrose Fleming, Thomas Edison was the one who later discovered the “Edison effect,” which says that electricity doesn’t definitely need a solid material to move through! It can move through gas or vacuums, too! Without this realization, vacuum tubes would never have been invented! Pretty awesome, right?
