and, it says 0.2 ohm... is that correct? that what it should be?
My DMM reads 0.6 ohms, does this mean the resistor is dead?

Re: Is there a polarity for this resistor?
When you touch the two leads from your DDM does it show 0.00 on the display? -

Re: Is there a polarity for this resistor?
OK. So when you touch the DMM's RED probe to the BLACK probe you see 0.6 Ohms....This means when you measure, you have to minus 0.6 form what is seen on the display........Then if it is 0.2....you should see 0.8.....minus 0.6 and you have 0.2.Comment

resistor is likely fine .. your meter or leads are in doubt .Comment

Re: Is there a polarity for this resistor?
That's why some multimeters have a button that says REL on them ... clean the leads of your multimeter (ideally use some isopropyl alcohol, but something abrasive works as well, basically to remove whatever oxides and crap is on the leads tips). Then press REL and now the multimeter should ignore the resistance of the wires in your leads. You should get a fairly good measurement of resistance from now on.
You'd have to use the REL button every time, most multimeters don't have memory to keep track of it.Comment

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
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 -
Hello;
I have an ASUS G14 GA401QM that currently has no 5v rail among other things stated below in points #3 and #4. I'd like to see if it's condition can be improved.
1) Originally this laptop had a problem with a shorted main power rail, so measuring at the current sense resistor after the DC IN FETs yielded a very low resistance. Before proceeding further I measured the CPU coils. We get 8.2 Ohms on the farthest right coil (PL8105) and 3.3 Ohms on the four to left left of it (PL8101 through PL8104). When I injected 1v into the current sense resistor, PQH9402 got warm.... -
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...
