WebJan 16, 2024 · 7. Determine the actual resistance of the resistor. Read the result shown on the multimeter. In determining whether or not the resistor is within the allowable range for that resistor, do not forget to take the resistor tolerance into account. [7] 8. Reattach a resistor that gives an accurate reading. WebA resistor is a passive component that reduces voltage or limits the current flowing through a circuit. This component can also absorb energy and dissipate this energy in the form of heat. Its resistance to the flow of electrons is determined by the conductive materials with which it is built. The materials used in the composition of a resistor ...

WebJan 6, 2016 · If the resistor breaks or has any issues it may cause the fans to only function on certain settings. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting.

WebSo what we have calculated is that these two resistors connected in parallel can be replaced by a single resistor of eight ohm. And nothing will change.
