WebApr 20, 2016 · If you put a resistor (say for an LED) on the positive cable then a short of the wire to the chassis will draw limited current. If you put the resistor on the return wire then a short to the chassis would blow a fuse or burn the wire up if it is not fused. A short on the return wire to the chassis will have almost no effect. Share Cite Follow WebAs others mentioned, the easiest way to drop the voltage is to put resistors in series from 12V to GND and measure the voltage between the different resistors and ground. Also, keep in mind that most digital voltmeters can be used to measure resistance. So you could also try that. 4. level 2.

WebAug 17, 2024 · 3. As the the other answers already said: When you read " a resistor reduces the current ", this does not mean, that the current after the resistor is smaller than before … WebResistance should be 60 ohms if both termination resistors are present. If measurement is 120 ohms only one terminating resistor is present, two resistors are required (see note below). If 40 ohms is measured a third terminating … imdb hitman\u0027s bodyguard\u0027s wife

WebI like to keep like-valued resistors taped together and stuffed into little plastic bags with the value written on the tape. I cluster a bunch of different values into one plastic bag, though. ... I use an Optivisor and fine-point forceps for digging the resistors I want out of that assortment and break into the taped bagged ones only if I can ... WebSep 2, 2014 · A resistor can only provided a fixed voltage drop if you send exactly the same current through it at all times. You would simply choose the resistor based on the amount of current so that it drops 7 V. But … WebResistors can get warm or even hot when in use. The range suggested in this lesson is selected to reduce warmth. Do not use resistors below 330Ω (ohm) for this ... longer than incandescent lightbulbs and do not break easily.
