@@bigpickles obviously there are some companies that operate differently but from what I've experienced alot of the hardware engineers around my area are contract workers. They get the contract and once it's completed if another one isn't open you are out of a job. Maybe it's different in your area but I'm around the space coast and most of them I've met have told me that. The ones I've met that are homeless were aged out and said it is hard to compete with the younger people getting out of school and willing to work for half what they were making.

Back in 2020, I was stuck at home due to Covid for my Circuits II class. For our lab assignments we were mailed the necessary components to create our circuits, which consisted of SMD resistors and capacitors. We were given extra parts for obvious reasons, and I am willing to bet that some of those SMD parts are still in the carpet.

My guess is protection and spread heat out. They are rated for 128mW and 5 LED would be 110mW of power through a single resistor.

@alexrudy6313 2 роки тому

@danielberei3021 2 роки тому
Yes you can. But, every LED has a slightly different voltage drop hence some will run on higher current and some less. On cheap LEDs you might even see some of them brighter and some dimner. Also you have to make sure the resistors wattage is rated above the current consumption of the total LEDs wattage/power.
@konstantin11 2 роки тому
Haha came to comments to say the same.
@PlayboyHZ 2 роки тому
In theory and paper this would work good but in real life LEDs dont have exactly the same characteristics. What then happens is that the diode with lowest forward voltage will conduct most of the current and it will wear out the fastest. After it dies (if it dies as open circuit) the diode with next lowest forward voltage will conduct most of the current and will die even faster than first diode and so on until you run out of diodes.
@EngineeringMindset 2 роки тому
As Daniel said, you could but it's not recommended. All the current will have to flow through it. Full explanation with examples here: ukposts.info/have/v-deo/b5RlraOhjG9_0oE.html

@miltonb4522 5 місяців тому
Definitely enjoyed the video but am rather curious as to why you didn’t just run the batteries in parallel to keep the 1.5v which would then mitigate the need for resistors as the LEDs could then handle the voltage although be just a bit dimmer. This way you’re not wasting energy and have double the capacity
@maynardr6 5 місяців тому
You can't reliably share current across LEDs like that for a number of reasons. The forward voltage to forward current relationship varies from one to the next enough to create large differences in the current. They'll also have a cascade failure eventually.

@meatbag8751 2 роки тому
So question, you add an individual resistor to each of the parallel paths surface mounted LEDs. What is the reason for not using a single resistor on the in path before the parallel? It doesn't seem like it could be redundancy, because from my understanding if one resistor fails that LED pathway will fail regardless, is it just failsafe so you can keep for working LEDs if a single resistor fails? Is it a ohms thing I'm not seeing? I've done my electrical engineering subjects but we haven't done much practical due to covid.
