What is the correct resistance measurement when the meter switch is set to the "2K" position?

When the meter switch is set to the "2K" position, it typically means that the meter is capable of measuring resistances up to 2000 ohms (2 kilohms). The setting allows the meter to read values in ohms ranging from 0 to 2000 as indicated by the specific range selection.

The correct resistance measurement given in this context is 500 ohms. This value is within the range that the "2K" position can accurately measure, indicating that the resistance being measured is lower than the maximum capacity of the 2 kilohm setting, which is appropriate since the meter is operating within the expected limits for a resistance measurement.

In contrast, the other resistance values presented, such as 250 ohms, 1000 ohms, and 750 ohms, could also potentially be read under different conditions or settings, but they do not meet the uniqueness of the specified query regarding the selected meter setting for the most accurate interpretation and use of the device in practical scenarios.
