SpletResistor Colour Code Examples. Q1) Determine the resistance of the given resistor with the given colour sequence (Red, Green, Red, Gold). As we know, the first two colours represent the significant digits of resistance value so the given colours represent digits 2 and 5. The third band is a multiplier band. SpletThe range to be used in measuring any particular unknown resistance (R x in figure 1-33) depends on the approximate value of the unknown resistance. For instance, assume the ohmmeter in figure 1-33 is calibrated in divisions from 0 to 1,000. If R x is greater than 1,000 ohms, and the R x 1 range is being used, the ohmmeter cannot measure it. handout literatur ddr
