Ending2: [step] An attempt to measure a resistor that is still connected to the circuit can yield an incorrect calculation, as part of the circuit might also be measured. [substeps] Disconnect one end of the resistor from the circuit. Ending3: [step] This can take a while, depending on what you're plugging it into. Look on the side of the circuit board. Ending4: [step] Run a wire cutter or other tool over a resistor and then pull it away from the circuit using the tip of a screwdriver to remove the resistor. These don't have a wire cutter for this.
