Not sure of the power draw on a circuit, the resisor specified is a 56 ohm 5 watt, what can I use that is cooler running? The resistor is used as a load on a 12v circuit.

Re: Cooler running resistor
A physically larger resistor like a 10 watt resistor will have less temperature rise because of its lager surface area. Or you could attach the 5 watt resistor to a finned heatsink.
Or use a high resistance if it doesn't cause other problems. -
Re: Cooler running resistor
any wattage resistor will get as hot . use a heat sink to dissipate the heat or install a fanComment

Re: Cooler running resistor
Keep in mind that those finned panel mount resistors are designed to have some sort of heat (like a ........ panel). Without that a 15W resistor might be 5-7 watts or something like that.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

by mikey5791Hi 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... -
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... -
by artvandalaiThe 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_rV7ui1Y3 Photos

by AstonishedHi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.

by FALKLANHowdy everyone! I hope all is well where ever you are!
I'm attempting to integrate a couple of LED pods into an automotive reverse lamp circuit. The problem being, while the vehicle is running there is a 8.5v current present on the reverse lamp power wire. Needless to say is that all LED pods and lights dimly illuminate while the 8.5v is present, so the LEDs are always powered on while the vehicle is running. When the vehicle is shifted into reverse, the voltage changes to 12 volts.
I am uncertain how to convert this line into a switched 12v output line for the LED pods.... - Loading...
