A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Use 2 E192 in parallel: a 6.19Ω resistor with a 4500Ω resistor. This gives 6.1846Ω which is close enough for rock and roll.
I feel like this is one of those comments I want to hoard in the off chance that I ever get into this and start building shit but I know deep inside me that's never gonna happen.
Just learn the math, it’s quite easy. IIRC you just add the reciprocals of the resistors then take the reciprocal of the answer.
1/Req = 1/R1 + 1/R2 + 1/R3 ….
Note that if it's a series circuit you simply add resistance.
I'm just an electrician though, we don't actually use the math or the theoretical stuff terribly often
