Quick question, I'm obviously a noob, what's the name of this?

Re: Diode or resistor
For clues look at the location number..
Rxxx = Resistor
Dxxx = Diode
Some are not so obvious for eg...
Lxxx = Inductor
etcComment

Re: Diode or resistor
Can someone tell me the correct number i should see on the multimeter when reading these resistors?

Re: Diode or resistor
As long as you don't go OL you can figure it out.
Set to whatever setting and check... if you get OL go up... if you get 0.002 go down etcComment

Hello Guys. Yesterday I was repairing a MacBook with no backlight. I noticed the resistor/diode RP802 is bad so I took it off. I also had a faulty motherboard that can't be repaired that had that resistor/diode on it (RP802). So it took the good RP802 off the faulty board. And when I had it on my tweezers it accidentally flew away. And now I don't know what to do. I 100% can't find it because of how small it is. Do you guys know any other diode/resistor that can work as the RP802
I'm a newbie to microsoldering and I'm still learning. All help is really appreciated

Good day folks. Today I had to work on a power supply/battery charger which had some parts arranged in a manner which intrigued me. It is a proprietary board that's part of an alarm panel and it also acts as a charger for a backup SLA battery. It's a very basic supply, with no proper battery management: have a look at the terminals and you'll immediately see how it works. There's a 14v output and there's a "BAT" output, which basically just ties the battery in parallel to the supply, but not directly, instead through a diode and resistor, as outlined on the doodles I did on the back....

I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short⦠that's not the direction they fail⦠or so I thought.
I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors... -
The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y -
I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out...
