If an analog meter is set to the R X 1k scale and reads 20, what is the resistance value?

• A. 2,000 ohms
• B. 20,000 ohms
• C. 200 ohms
• D. 20 ohms

Answer: (B)

When an analog meter is set to the R X 1k scale, it is measuring resistance and is calibrated so that the reading on the dial represents the resistance value in thousands of ohms. In this case, if the meter reads 20, that reading must be multiplied by the scale factor to determine the actual resistance. Since the scale is set to R X 1k, you multiply the reading by 1,000. Thus, a reading of 20 on this scale means: 20 (reading) x 1,000 (scale factor) = 20,000 ohms. This is the method used to interpret the reading correctly when dealing with different ranges on an analog meter. Understanding the scale setting is crucial for converting the dial reading into an actual resistance value. In this question, the proper interpretation leads us to the conclusion of 20,000 ohms as the correct answer.
