You only just touched on what i think is the best use of the zero ohm resistor, to join grounds. For low oise in adc, audio, etc its good practice to keep grounds apart until the last possible point. If its a single pin on a connector the zero ohm resistor allows each ground track to be a different net which stops the cad software joining them together
dear teacher Thank you very much for visiting my channel and commenting. I read your bio and I'm proud that you paid attention to me. I hope to always use your opinion in my work. thank you so much
I use 0 ohm resistors in all of my PCBs: 1. Easy to isolate power rails on components if there is a failure. if your not sure if where the short is, you can remove the resistor & see if the short goes away 2. For Jumpers. If your PCB has several different configurations, you can solder them as jumpers. I also use low ohm resistors on some digital busses that might be exposed to transient voltage spikes (TVS), and use TVS diodes so if a peripheral chip (ie Port) gets hit with a TVS it does not damage other components connected to the same bus. I do try to avoid using them for Jumpers for running perpendictuar traces between the pads as it could introduce noise in the trace.
Them also work nice as small insulated jumpers, in places where a simple wire and the solder mask wouldn't offer enough insulation, but a plastic insulated wire would be overkill.
I use it in prototypes when want to have opportunity to install actual resistance if it needed. For example between GND and potentiometer and Vss and potentiometer, so if needed I can make band of possible values of voltages from pot more narrow.
They can be used as a jumper, or on a prototype board where a resistor was assumed to be needed, and is not in later revisions. They're also useful if you want superconductivity, as even copper traces have some resistance.
I sometimes use them to add options to a circuit, and place a hole through the pcb beneath them. They can then be pushed off the board using a sharp point through the hole (no desoldering needed).
3:48 I think the Zero Ohm resistor itself is not directly reducing the noise between two ground. But it force the PCB layout to form a star ground. Sometime Digital and Analog ground is essentially same ground (in the DC point of view of course). But It's really hard to keep track of different ground that came from same ground when designing the PCB. You either consciously Separate Digital and Analog plane and connect them with a single point to form a star, or you can use zero ohm resistor to create a net separation. So you can technically separate Digital and Analog ground.
Hi Teacher! Thanks for sharing such hidden information intentionally not discuss such subject "zero resistance". It great idea to measure the current across it and find equivalent. Since there is no option to share a case (diagram) which I am facing... Kindly share your WhatsApp contact or email address. Brief of my case: There are two.Op amps: From an electrical AC mains 3phase... Reduced direct voltage upto 3mv AC use of series resistor bank and fed to one of Op amp (+). (-) Input was fed above zero value resistor (let's say vertically placed) which is connecting "top end" to Chassis ground and bottom to control ground. Caused due to a surge now that zero ohm resistor has been damaged. Wondered ...... Even marked as 0-Ohms.... Will it be there resistor value less than zero... Since it just looks like tiny mV value fed to (-) terminal of Op amp and stop passing the signal gain to output of the Op amp in case of open CCT that 9Ohms resistor.... Kindly advice how could find the value of resistor since the manufacture refuse to give exact details or component. Thank you!
Thank you very much for the valuable comment. You know that talking about electronics should be documented. Since I haven't seen the circuit yet, I can't give a proper opinion. But in such cases, it is better to calculate the resistance size by determining the current and voltage.
The device or the factory calibrates the 000, 100 and 200 types by memory effect inside the resistor, that's why they exist. Also serves as a fuse to avod burnout or accident. The cheat to reach the luxury mode of devices, is the radiatin from heavy power banks or from car battery for 3 days. When you use this fix, you have to psition the power bank each 3 days to other areas of the device. A bigger tab may take 2 weeks to be fixed this way. Best try with old Nokia battery , the electronic part of the batt will become hot, the phone will become cold. The middle cnnection must be clean, because it will come in use. By default, the mid connection is nothing in phones.
when employed strategically they can often let you get away with one-sided PCB instead of two, with all benefits of reduced cost and work. I used it a lot back in the years when I etched my own boards (now I just order them, lol).
Thank you for your opinion. It is a misconception that this resistance is only considered as a fuse. The use of this resistance is more than a simple fuse
In modern times, these 0 OHMS resistors act as time machines. Once burnt and fly away. It is hard to repair if U can not find another similar PCB. U don't know what is? What type of electronic component , capacitor ? resistor ? fuse ? After killing your time, hard to repair, then, throw it away.
thank you very much It is absolutely true. The existence of these resistors causes a lot of confusion in the circuit, especially if it is the first time you repair a circuit.
Hello, excellent professor as always. I had a question about the Pride horn! Why the horn sound is weak and it doesn't beep from time to time. I even adjusted the adjustment screw. And it says 333 Hz on the horn.
Pick and place machines started in the era of through hole components, so machines capable of cutting wire and placing a through hole jumpers existed by the same time first surface mount componets and placing machines for them appeared. Through hole P&P machines are rare and far more expensive because they are much more complicated and with most of the manufacturing market nowadays orinted at cheaper SMD they are probably no longer a bulk list products and everything made by order is very expensive and even more so because mass production is historicly done by cheap labor.
@Electronic4U-david I can't name my comment an opinion, just sharing information. In Bugaria, after communist regime collapsed in the early 90s, I a couple of times visited a PCB population facility, and in my opinion, in this context it doesn't matter whether equipment was bought before the end of 1989 or it was an investment of "disappeared party money" and dissappeared finances of the government founded abroad companies. Machines for placing of wire leaded components are more complicated than these for SMD because they have modules for leads forming and cutting and in the facility I'm describing here these sections were used to form components for manual populating as well. These first sections could do not only axial lead components on paper tapes or sticky tape chains, but also could take, form and cut i.e. radial leaded electrolytic capacitors from boxes.
It's not zero, it's just negligible. And, depending upon the design of the resistor itself it could be lower resistance than the traces that you're using.

Zero ohm resistors are far cheaper than chip fuses so if the part of the circuit that needs over current protection is not requiring a critical value then selecting a zero ohm resistor with a close wattage tolerance works just fine.. This has been adopted by most manufacturers to cut costs while providing over current protection.. Purist's will claim this is somehow bad practice but you can't argue the fact that it works..
Hello teacher, I wanted to thank you because you teach so beautifully in your explanations in your channel and you say it in such a way that everyone understands and I took many of my ideas from your channel. I wish you success and thank you in my messages. Answer me. Thank you. Thank you
the 0-ohm resistor really is just a miniature version of jumper wires. and also easier for machines to place
Thank you for your opinion. Yes, that's right
Thanks for great nutshell summary!
so why not use diodes
@@sanfrrraa Do those exist? I did a quick search and I couldn't even find any information on them.
that's what I always used them for.

Hello, thank you for your support.
Is it superconductor at room temperature?
Unfortunately, I do not have the necessary tools for this test

And can be installed using SMT pick and place machines.

Welcome
I see them used a lot as fuses in old nintendo stuff.
Thank you for your opinion. Yes, it is absolutely true. There are countless uses
also so people can't pirate nintendo, right?

What 0 ohm . This is called a fuse. Now we are reinventing electronics
Thank you for your opinion. It is a misconception that this resistance is only considered as a fuse. The use of this resistance is more than a simple fuse
Beneath that zero ohm resistor depending on tis size you can make 2 to three tracks or traces. It's the PCB designer's best friend.
thank you very much It is absolutely true
I've also used them to make my final circuit look symmetrical lol (this was a thru hole board)
Thank you for your valuable opinion. Good idea
So, how can I tell the difference between
a zero ohm 1/4 watt resistor and
a zero ohm 2 watt resistor?
Resistance size. Circuit current is important
could it be used between isolated wire ? As a wireless excess absorber to prevent false signal over time spike ?
No, I don't think so
In modern times,
these 0 OHMS resistors act as time machines. Once burnt and fly away. It is hard to repair if U can not find another similar PCB. U don't know what is?
What type of electronic component , capacitor ? resistor ? fuse ?
After killing your time,
hard to repair,
then, throw it away.

thank you very much
Thank you s much
You are most welcome
How do you have a 0 ohm resistor without a cryogenic cooled superconductor?
It's not zero, it's just negligible. And, depending upon the design of the resistor itself it could be lower resistance than the traces that you're using.
Thank you very much for your valuable opinion
Thank you for your opinion. I said in the video that the value of these resistors is not zero and they always have a small impedance
