Here’s an excerpt: “A diode lets electrons flow in only one direction. It works like a switch: when current is flowing one way, the switch is on, but when current tries to flow the other way, the switch turns off. Sir John Ambrose Fleming is best known for inventing the diode, originally called the kenotron.”
