Everyone knows about light-emitting diodes, but did you know there are also light-emitting capacitors? that's what EL wire is!
there's also light-emitting resistors (more commonly called incandescent light bulbs), but we're not aware of any light-emitting inductors

@socks because Physics, inductors are physically larger and heavier than capacitors and so whenever possible they're avoided in electronics, so you'll see a lot more capacitors than inductors -F
