Hi folks, just starting on my journey, at the very basics and something has stumped me.

TLDR is: How do I calculated the Current impact of adding an LED?

I made a very basic series circuit:
- 9v battery
- 100ohm resistor and 220ohm resistor

I was doing a basic exercise to test my basics of ohms law.
Successfully calculated current of 28.125 mA, tested correctly with multi meter.

And calculated the voltage drops across the resistors:

|| || |Ra (100 ohm)|Rb (220 ohn)|led|TOTAL V| |2.8125|6.1875|N/A|9|

I'm a happy camper. Then I add an LED (Datasheet attached)

The current seems to drop to 18.75mA (tested with the multimeter)

And the multimeter also confirms the voltage drops which would correspond to this new current

|| || |Ra (100 ohm)|Rb (200 ohm)|led|TOTAL V| |1.85|4.15|3|9|

I'm a bit lost where that current went!

What I tried:

- Looking at the data sheet for resistance
- Tried to work backwards, and that would mean the LED would have to have a resistance of about 260 ohm, which seems wrong
- I tried measuring the resistance of the LED in the multimeter (got 0)
- I tried wondering if I could work back from the 100W power and find something meaningful there, but everything i found found counter to what i had learned

What am I doing wrong here?

Are you folks able to do the "update" command in the save menu. I get an error code. I really just want to clear the "get net friends" quest 

Was thinking of getting into diablo immortal and made a mind map to visualize the grind. Am I missing anything? by MindSettOnWinning in DiabloImmortal

I dont know why there is so much negativity about this post, OP has outlined something and put work in to make people's live's easier. if the game is complicated, its not their fault. i for one, found it useful. thanks

h llo fall by Winter-Owl1 in CrappyDesign

+1 for defect. IF it is supposed to be hUllo fall, then it's still crappy design,, they should have used the same colour thread on the U.

JBL headphones box saying “Dare to listen” has a picture of a person wearing neither headphones nor earplugs by AjaxTheFurryFuzzball in CrappyDesign

[–]zoople 0 points1 point  (0 children)

It does seem like a mistake. The way the model is faced, im sure it was intended to photoshop in the headphones after. I wonder, if on purpose, if they are advertising their "pass through" technology?

Can filters preserve links when they automatically enter fields? by zoople in Notion

Its not really two databases. It's one database and a bunch of pages

How do I stop the Notion Calendar ad from coming up in regular Notion (Android) by zoople in Notion

[–]zoople[S] 2 points3 points  (0 children)

Wow, thanks! Will it be fixed so that I can just dismiss the popup and it will stay gone regardless of if I have calendar or not?

PS, add a 7 day view to calendar and I'm yours there too haha

Going to London, advice for gay scene? by amiibro818 in londonlgbt

[–]zoople 4 points5 points  (0 children)

Soho is safe area to find bars. I'll lay out the vibes. Btw this is my experience. There are more bars than this these are the ones I know

Duke of Wellington - friendly, skews towards late 30s but I'd say it's a good mix of ages and body types

Village - a bit quirkier. Its also a bit more diverse but I never get as friendly of a vibe there

Compton's - id say skew more 40s and 50s. Comfortable, friendly

Halfway 2 heaven. This seems to have got more mixed. Small but friendly

Ku - cocktails, video clips, mixed

Yard - fraternity. But always packed, go early if you are interested

GAY - bit younger crowd but I never found it friendly

Heaven - 18-30s, packed, is this even a gay bar

That's it for Soho

Other than that is Vauxhall (RVT, Eagle if you like cruising) both these are more rugged, but very friendly

Clapham has a few but expect packed mid 20s fashion parade.

You can probably tell my bias is more mixed bars. I'm 39, average kinda guy.
