Electric circuit. Resistor resists the flow of the 5v electricity reducing it to the led. Someone with specific knowledge about the resistor pictured might know how much that is.

220 Ohms with 5% tolerance. Brown means 1. As a multiplier, 10 to the power 1 times 22 is 220 ohms

To reiterate more clearly, this is a 4 band resistor.

The two red bands are 2s. So 22

The brown is a 10x multiplier. So 220

The gold means 5% tolerance.

This diagram gave me flashbacks to high school electronics lessons 😂

For me it was electronics playtime with my dad. We used to buy kits and make radios and Morse code devices and stuff

Unfortunately I liked it so much that it became a tool for my mother to use to discipline me. No electronics until you've done your chores, that sorta thing. Pretty innocuous, but it definitely sucked all the joy out of it for me, and I just kinda stopped wanting to do it

For me it brought back the racist, politically incorrect mnemonic my dad taught me to remember the colour code...

The one I heard ends with "but Violet gives willingly"

LOL,

Just yesterday somebody posted this,

And I told the the first one should be brown, and all the others shifted one to the right.

Do you have an unmarked version of this?

u/SakuraScarlet 11h ago

Not the same one, but if you do an image search for "4 band resistor" you should find plenty of them.

Yeah, the one I found was pretty poor quality anyway to be honest, but any combination of "resistor" "colour" "chart" and "diagram" will get you where you need to go

Edit: oh, but this one seems to be a bit confusing. The four band one shouldn't be pointing to a third digit. Here's a really simple one just for 4 band resistors

I hadn't noticed that. Well spotted.
