The space-saving Vishay Techno CDMV series provides a single-component replacement for multiple discrete resistors used in voltage division applications for industrial and alternative energy equipment.
What do you do when you dont have a resistor of the correct value? Put 10 in parallel on a lasercut pcb of course
Resistor network
Note the many parallel paths between each pair of electrodes, with some paths cut by laser to trim the resistance value

I was quite the nerd in my youth. I used to ride my bike to the Radio Shack to pick up stuff like this. I found these in a bucket of junk that I've had for at least 25 years.
This resistor is exactly the same as the dim dip resistor, but it is part of the fan system. Some 106 S2 models have a two speed rad fan. The resistor comes into play when the fan is on its lower of the two speeds.

I finally got the missing parts. The solder bridge has been replaced with a proper 0-Ohm resistor as well ;-)
my submission to resistor's "24kt Floppy" project.
nabbed this from his profile because I forgot to take a picture before sending it out.
This picture has another complex, multi-branched circuit, much like the one in the video you just watched. The process is the same: Progressively make the circuit more simple, by combining like resistors. Pay attention here how the original circuit 0 became circuit 1, then 2, then 3, by combining resistors using the rules for series and parallel.
Once you're down to one resistor (circuit 3), you can start using Ohm's law (V=IR) to get the overall current. This is the current through the 3ohm resistor. You then backtrack to circuit 2, and use Ohm's law on each resistor to get the voltage for the 3 ohm and all of the parallel branches. You can check here using Kirchhoff's loop rule whether your voltages all add up to 12. Then backtrack to circuit 1, and get the current through each parallel branch. Kirchhoff's junction rule tells us that these should all add to the overall current you already calculated, 2.33amps. Finally, use circuit zero (the original) to get the voltage of the two resistors on the green branch.
The last step is to get the power of each device. That's easy- just use P=IV and multiply voltage and current for each resistor. The ones with the most power will dissipate the most heat, and if they were light bulbs, they'd burn the brightest.

Start with the resistors. They have no polarity, so the direction doesn't matter. You can put all of them all at once if you like.
A really audio card from an old PC (I guess). It was more than 25 cm long!
Some kind of ISA 32 maybe...
Vishay’s new PHP series of precision high-power thin film chip resistors features a low absolute TCR of ± 25 ppm/°C, tolerances down to ± 0.1 %, and high power ratings of 1.0 W in the 1206 case size and 2.5 W in the 2512 case size. (For hi-res version, select "View all sizes" from Actions pulldown menu above.)
Chip resistors limit DC or AC current. They are used to control the current flow in a device or system and to drop the voltage or maintain the current at a certain level. Further, they are used in various applications such as consumer electronics devices, industrial automotive and others. They can be used to protect, operate, or control circuits.
Chip resistors have the potential to enhance and even replace existing technology solutions within enterprise supply chains and change the structure of the work environment. Companies manufacturing chip resistors are demonstrating use cases that lead to increase in workplace efficiency, productivity, and compliance, which is expected to be lucrative when the technology matures.
Three resistors made from nichrome wire or similar. I think what I'm holding there is about 23 years of air con intake detritus that, due to its insulating properties, increase the temperature of and accelerated the corrosion of the three resistance wires which, when connected in series with the air con blower motor at 12V, make it turn at a range of speeds.
Measuring (using that term loosely, don't trust these numbers) the original resistance wires:
Between terminals M1 and L, ~0.2 mm diameter, 8 wraps of 6 mm diameter gave about 1.6 ohm.
Between terminals M1 and M2, ~0.25 mm diameter, 8 wraps of 8 mm diameter gave about 1.4 ohm.
Between terminals M2 and H, ~0.3 mm diameter, 8 wraps of 10 mm diameter gave about 1.0 ohm.
See flic.kr/p/Fa7MEH for my repair job.
